## FREE PUBLIC LECTURE – Statistics in the Headlines

FREE PUBLIC LECTURE
Wednesday, October 20, 2010, 4:00-5:30 pm
Room 2117, Sidney Smith Hall, 100 St George Street, Toronto

Statistics and probability have appeared in major news stories with
greater and greater frequency.  Recent examples include heated political
upcoming mayoral election, the spike in Toronto pedestrian deaths last
January, fascination with the odds of winning huge Lotto Max jackpots,
unexpected outrage about excessive lottery "insider wins", a recent
television documentary about mysterious coincidences, and the surprisingly
high-profile summer controversy about cancelling the long-form census.
This talk will consider such questions and controversies from the
perspective of a statistics professor who conducted numerous media
interviews upon the success of his general-interest book "Struck by
Lightning: The Curious World of Probabilities".

This event is presented in conjunction with the United Nation's designated
"World Statistics Day" (http://unstats.un.org/unsd/wsd/).

Absolutely no mathematics or statistics background is required to attend.



## MGSA Beginning-of-Year Social

As a part of the (unofficial) graduate orientation, you are all invited to
MGSA (Math Graduate Student Association)'s Beginning-of-Year Social event!
To break the pub-going tradition (as some students are not completely
comfortable in pubs) and to enjoy the last bit of summer, we will have an
outdoor picnic dinner at High Park this time (weather permitting). :-)

[In case of sun and very light rain, we will head to High Park from the
department together.  You can do any of the park activities you like
(bring your own equipment, e.g. frisbees, balls), picnic lunch, then more
exploring.]

MEETING PLACE: Math Lounge (Bahen 6th Floor, circular area)
MEETING TIME: Thursday, September 9 at 3:30pm (will wait for 15 minutes)
ESTIMATED EVENT RUNNING TIME: 3:30-8pm (before it gets dark out)
LURING FACTORS (besides being in good company): All attendants who are
members of the department will receive a $5 food/drink cash subsidy. But you are responsible for bring or buying (from the restaurant at High Park) your own dinner (and drink). A variety of natural juices will be provided. TRANSPORTATION: We will use the TTC, and maybe try to take advantage of one of their group discounts. ABOUT THE PARK: www.highparktoronto.com. High Park is a large park and one of those places in Toronto you must know and visit if you live here. The earlier you find out about it, the better! [In case of heavy rain, we will play games and chat at the department from 3:30-5:30pm, and then head over to dinner together, and hopefully a kind and powerful restaurant will have pity on us. (I'll try to make reservation on the day. Our worst enemy and loyal friend will be pizza.)] MEETING PLACE: same. MEETING TIME: same. ESTIMATED EVENT RUNNING TIME: same. LURING FACTORS: same ... or maybe$5/person-equivalent subsidy depending
on format of food.
TRANSPORTATION: simplified.

Please come and mingle with each other, and get to meet the new students
first hand!  New faces are most welcome!  Feel free to bring your
partner(s) and kids (if you have any).

Looking forward to meeting/seeing everyone!

## Departmental PhD Thesis Exam – Mikhail Mazin

Everyone is welcome.  Coffee will be served in
Math Lounge before the exam.

Departmental PhD Thesis Exam
----------------------------

Wednesday, April 21, 2010, 1:10 p.m.,
in BA 6183, 40 St. George Street

PhD Candidate:  Mikhail Mazin

Thesis Title:  Geometric Theory of Parshin Residues.
(http://www.math.utoronto.ca/mmazin/thesis.pdf)

Thesis Abstract:
In the early 70's Parshin introduced his notion of the
multidimensional residues of meromorphic top-forms on
algebraic varieties. Parshin's theory is a generalization
of the classical one-dimensional residue theory. The main
difference between the Parshin's definition and the
one-dimensional case is that in higher dimensions one computes the
residue not at a point but at a complete flag of irreducible
subvarieties X=X_n\supset ... \supset X_0,  dim(X_k)=k.
Parshin, Beilinson, and Lomadze also proved the Reciprocity Law
for residues: if one fixes all elements of the flag, except
for X_k, where 0<k<n, and consider all possible choices of X_k, then
only finitely many of these choices give non-zero residues, and
the sum of these residues is zero.

Parshin's constructions are completely algebraic. In fact, they
work in very general settings, not only over complex numbers.
However, in the complex case one would expect a more geometric
variant of the theory.

In my thesis I study Parshin residues from the geometric point of
view. In particular, the residue is expressed in terms of the
integral over a smooth cycle.  Parshin-Lomadze Reciprocity Law for
residues in the complex case is proved via a homological relation on
these cycles.

The thesis consists of two parts. In the first part the theory of
Leray coboundary operators for stratified spaces is developed.
These operators are used to construct the cycle and prove the
homological relation. In the second part resolution of singularities
techniques are applied to study the local geometry near a
complete flag of subvarieties.


## Departmental PhD Thesis Exam (Jana Archibald)

Date and Time:  Tuesday, April 13, 2010, 11:10 a.m., in BA 6183, 40 St. George Street

PhD Candidate:  Jana Archibald

Thesis Title:   The Multivariable Alexander Polynomial on Tangles
(http://www.math.toronto.edu/jfa/jana_thesis.pdf)

Thesis Abstract:

The multivariable Alexander polynomial (MVA) is a classical invariant
of knots and links. We give an extension to regular virtual knots which
has simple versions of many of the relations known to hold for the
classical invariant.
By following the  previous proofs that the MVA is of finite type  we
give a new definition for its weight system which can be computed as
the determinant of a matrix created from local information. This is an
improvement on previous definitions as it is directly computable (not
defined recursively) and  is computable in polynomial time.  We also
show that our extension to virtual knots is a finite type invariant of
virtual knots.
We further explore how the multivariable Alexander polynomial takes
local information and packages it together to form a global knot
invariant, which leads us to an extension to tangles.    To define this
invariant we use so-called circuit algebras, an extension of planar
algebras which are the `right’ setting to discuss virtual knots.  Our
tangle invariant is a circuit algebra morphism, and so behaves well
under tangle operations and gives yet another definition for the
Alexander polynomial.  The MVA and the single variable Alexander
polynomial are known to satisfy a number of relations,  each of which
has a proof relying on different approaches and techniques.  Using our
invariant we can give simple computational  proofs of many of these
relations, as well as an alternate proof that the MVA and our virtual
extension are of finite type.
