Dear students and postdocs,

There will be an industrial problem-solving workshop at the CRM in
Montreal August 15-19.  To learn more about the workshop:

To learn about the problems that will be studied:

There are some funds available to support graduate students.  There may
also be funds to support postdocs --- I don't know.

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 83.4

where 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:

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

and the timetable at

The steps to enrol in courses are as follows      

1.  request course selection on anytime from 
    August 8, 2011 to September 21, 2011.

2.  submit enrolment form (
    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,
    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

If you have any questions on the above, or any other matters, please
do not hesitate to contact me at

Are you the first in your family to attend graduate school? 
Join us for a coffee social on Tuesday, June 28th at 5:00pm at the 
Grad Room.

· Meet and connect with others who are the first in their families to 
pursue higher education

· Graduate students from all disciplines are welcome to attend this 
informal social

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.

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 

 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 

Looking forward to seeing you there!

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

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: <>

  Hoping to see you there,
          Walter and Catherine
