Thesis Title: On van der Waals forces

Thesis abstract:The van der Waals forces, which are forces between neutral atoms and molecules, play an important role in physics

(e.g. in phase transitions), chemistry (e.g. in chemical reactions) and biology (e.g. determining properties of DNA).

These forces are of quantum nature and it is long being conjectured and experimentally verified that they have universal

behaviour at large separations: they are attractive and decay as the inverse sixth power of the pairwise distance between

the atoms or molecules. In this thesis we prove the van der Waals law under the technical condition that ionization energies

(energies of removing electrons) of atoms are larger than electron affinities (energies of adding electrons). This condition

is well justified experimentally as can be seen from the table,Atomic number Element Ionization energy Electron affinity

------------ ------- ----------------- -----------------

1 H 313.5 17.3

6 C 259.6 29

8 O 314.0 34

9 F 401.8 79.5

16 S 238.9 47

17 Cl 300.0 83.4where we give ionization energies and electron affinities for a small sample of atoms, and

is obvious from heuristic considerations (the attraction of an electron to a positive ion is

much stronger than to a neutral atom), however it is not proved so far rigorously. We verify

this condition for systems of hydrogen atoms. With an informal definition of the cohesive

energy $W(y)$, $y = (y_1, ..., y_M)$ between $M$ atoms as the difference between the lowest

(ground state) energy, $E(y)$, of the atoms with their nuclei fixed at the positions

$y_1, ..., y_M$ and the sum, $\sum_{j=1}^M E_j$, of lowest (ground state) energies of the

non-interacting atoms, we show that for $| y_i - y_j |$, $i,j \in \{ 1, ..., M \}$, $i \ne j$,

large enough,$$

W(y) = \sum_{i<j}^{1,M} \frac{\sigma_{ij}}{`|y_i-y_j|`

^6} + O ( \sum_{i<j}^{1,M} \frac{1}{`|y_i-y_j|`

^7} )

$$where $\sigma_{ij}$ are in principle computable positive constants depending on the nature of the atoms

$i$ and $j$.

The 2011-12 Graduate Studies in Mathematics Handbook is now up on the web: http://www.math.toronto.edu/cms/assets/MathFiles/Graduate/Files/2011-12GradHandbook.pdf Hard copies of the handbook will be placed in student mailboxes within the next several weeks.

The 2011-12 mathematics graduate course descriptions and tentative timetable are finally on-line. The timetable is still a work in progress. You can find the descriptions at http://www.math.toronto.edu/cms/tentative-2011-2012-graduate-course-descriptions/ and the timetable at http://www.math.toronto.edu/cms/tentative-2011-2012-graduate-course-timetable/ The steps to enrol in courses are as follows 1. request course selection on www.rosi.utoronto.ca anytime from August 8, 2011 to September 21, 2011. 2. submit enrolment form (http://www.sgs.utoronto.ca/Assets/SGS+Digital+Assets/current/Student+Forms/Enrollment_Form.pdf) to Ida to get requested course(s) approved. Course selection will be approved soon after an enrolment form is received. 3. If you wish to register in an undergraduate course for non-credit, graduate students can start to request from August 11. Courses are first open to the undergraduate student body. Please note that there may be limited enrolment and you may be on a waiting list. The sooner you request undergraduate courses the better; they fill up quickly. 4. Any courses, graduate or undergraduate, taken from another department will require the approval of the other department before math department approval. Such approval can be obtained on the enrolment form (see item 2. above). 5. If you need help selecting courses, please contact our graduate coordinator, Prof. Dror Bar-Natan, at drorbn@math.toronto.edu, for advice. 6. The absolute deadline to obtain course approval is September 26. Beyond this date, a petition will be required for School of Graduate Studies. If you have any questions on the above, or any other matters, please do not hesitate to contact me at ida@math.toronto.edu. Ida

The following information has been sent to all currently registered students from SGS. It is important to note the following: PhD students who commence their progam after September 1, 2010 -------------------------------------------------------------- For PhD students who begin their program after September 1, 2010 and who do not complete their PhD within the time limit of six years, lapsed registration will no longer be allowed, Lapsed registration is the current practice for students who started before September 2010. Mandatory registration will be required. You can apply for extensions to a maximum of 4 years. The first two extensions require only departmental approval, the remaining two must have approval by both the department and SGS. If you do not complete the PhD within this 10 year period, the degree is forfeited. In the extension years, all PhD students will pay fees at 50% of the domestic rate, plus sessional incidental and ancillary fees. PhD students who commenced in September 2010 -------------------------------------------- This group may lapse and seek reinstatement only if they are still within the maximum allowable time for the degree program (10 years). Reinstated PhD students must pay fees for any session(s) in which they did not register including program extension fees. PhD students who began their program prior to September 1, 2010 --------------------------------------------------------------- These students have two options. They may "opt-in" to the new extension arrangements listed above or they may follow the regulations that were in place when they began their program. Students who do not "opt in" and seek a program extension after the six-year period will be assessed full-time fall/winter program fees for the extension period. This may be all very confusing, so if you have any questions please just drop by my office and we can discuss this on an individual basis. Thanks, Ida

Dear all,
This is a reminder that the MGSA is organizing a Midsummer Potluck
Dinner and Ceili that will take place at the Hart House Music Room
on Saturday June 25th, at 7pm. Ceili will begin at 8pm.
Bring your family and friends, your favourite dish and enjoy an
evening of Irish music and dance in the beautiful architectural
setting of Hart House!
Ceili is a traditional Irish social gathering with music and dancing.
There will be a professional ceili caller (a person who explains easy
ceili dances), so no experiece is necessary to participate. Some of
you already did ceili at the Halloween potluck last year.
Please RSVP by Monday, June 20th to nataliya.laptyeva@utoronto.ca
indicating
1) how many guests will accompany you, and
2) what food are you planning to bring (so that we don't end
up with 20 desserts).
Please bring the amount of food that is enough for you and your
guests.
Looking forward to seeing you there!
Nataliya

DEPARTMENTAL PHD THESIS EXAM
----------------------------
Friday, June 17, 2011, 3:10 p.m., in BA 6183
PhD Candidate: Brian Pigott
PhD Advisor: James Colliander
Thesis title: Low Regularity Stability for Subcritical Generalized
Korteweg-de Vries Equations
Thesis abstract:
In this thesis we prove polynomial-in-time upper bounds for the
orbital instability of solitons for subcritical generalized
Korteweg-de Vries equations in $H^{s}_{x}(\R)$ with $s < 1$.
By combining coercivity estimates of Weinstein with the $I$-method
as developed by Colliander, Keel, Staffilani, Takaoka, and Tao,
we construct a modified energy functional which is shown to be
almost conserved while providing us with an estimate of the
deviation of the solution from the ground state curve. The iteration
of the almost conservation law for the modified energy functional
over time intervals of uniform length yields the polynomial upper
bound.
A copy of the thesis can be obtained by contacting
bpigott@math.toronto.edu.
Refreshments will be served in the Math Lounge before the exam.

Dear All, We are running a workshop on mathematics and oceanography at the Fields Institute on June 13 - 16, 2011. The purpose is to bring together mathematicians and ocean scientists to confer on the present state of research and the current body of knowledge on ocean dynamics, and in particular on tsunami predictions and the dynamics of rogue waves. There is a sense of urgency in the ocean sciences and the mathematics communities over these questions, due to the very recent tsunami disaster in Japan. Our purpose is to inform the mathematics community about problems of prediction and of description of extreme ocean waves, and in particular the role that can be played by mathematical tools and techniques. As well, our purpose is to provide a venue from which collaborations are developed between the two communities of mathematicians and ocean scientists. You are all welcome to attend the workshop, which has no registration fee. More information is available at the Fields Institute website: http://www.fields.utoronto.ca/programs/scientific/10-11/seawaves/ <http://www.fields.utoronto.ca/programs/scientific/10-11/seawaves/> Hoping to see you there, Walter and Catherine
