of Waterloo\n\n\n\n'A Note on Geometric Theories of Fields'\n\n\n\nWill Jo
hnson and Jinhe Ye have shown equivalence conditions on expansions of very
slim fields\, strongly geometric fields and algebraically bounded fields.
As a consequence\, we get a one-cardinal results for definable sets and p
ositive dimensional interpretable set. We will work though this paper\, en
titled 'A Note on Geometric Theories of Fields'.\n\n\n\nMC 5417

DESCRIPTION:Spiro Karigiannis\, Department of Pure Mathematics\, University
of Waterloo\n\n\n\n'The geometry of G2 manifolds: a marriage of non-assoc
iative algebra and non-linear analysis'\n\n\n\nThis is a practice run for
a colloquium talk that I am giving at Florida International University dur
ing reading week. I want to make sure it is pitched at the right level for
a general colloquium\, and also that it does not go over the allotted tim
e of 50 minutes. So I would welcome any useful feedback that you can give
me. However\, it should also be a useful introduction to G2 manifolds for
graduate students who are not experts on the subject. Here is the official
abstract:\n\n\n\nI will spend the first part of the talk giving a gentle
introduction to G2 manifolds\, with a special emphasis on their similariti
es and differences with Kahler manifolds. In the second part\, I will focu
s on some recent work with Daren Cheng (Miami) and Jesse Madnick (Oregon)
on the analytic properties of a special class of maps into G2 manifolds\,
which are analogues of J-holomorphic maps in Kahler geometry. The talk sho
uld be accessible to a general mathematical audience.\n\n\n\nMC 5479

DESCRIPTION:Camila Sehnem\, Department of Pure Mathematics\, University of
Waterloo\n\n\n\n'C*-envelopes and semigroup C*-algebras'\n\n\n\nThe C*-env
elope of an operator algebra C is the smallest C*-algebra generated by a c
ompletely isometric copy of C. In this talk I will consider the C*-envelop
e of the non-selfadjoint operator algebra generated by the canonical isome
tric representation of a semigroup P on $\ell^2(P)$\, where $P$ is assumed
to be a submonoid of a group. I will show that the C*-envelope of this a
lgebra is canonically isomorphic to the boundary quotient of the Toeplitz
algebra of P. If time permits\, I will discuss a similar result in a more
general setting\, in which the semigroup of isometries is replaced by a pr
oduct system of C*-correspondences.\n\n\n\nThis seminar will be held both
online and in person:\n\nRoom: MC 5479\n Zoom link: https://uwaterloo.zoom.

DESCRIPTION:Patrick Ingram\, York University\n\n\n\n'Variation of canonical
heights in arithmetic dynamics'\n\n\n\nThe Néron-Tate height on an abelia
n variety is an important measure of arithmetic complexity\, for example y
ielding information about the structure of the group of rational points. A
1980 result of Silverman gives an asymptotic for the variation of this he
ight along a section of a family of abelian varieties. One may construct a
n analogous canonical height function associated to a polarized algebraic
dynamical system\, and in this talk I will survey some recent refinements
of the analogue of Silverman’s theorem.\n\n\n\nMC 5501

sor function and random matrix distributions'\n\n\n\nThe divisor function
gives the number of positive divisors of a natural number. How can we go a
bout understanding the behavior of this function when going over the natur
al numbers? In this talk we will discuss strategies to better understand t
his function\, issues related to the distribution of these values\, and co
nnections to the Riemann zeta function and some groups of random matrices.
