DESCRIPTION:Title: Mathematics of Apportionment\, or Why We Can't Have Nice Things\n
by Corrine Yap as part of Pizza Seminar\n\n\nAbstract\nHow are the delegat
es in the U.S. House of Representatives assigned? Why does Georgia get 14
while Alabama gets 7? What makes an apportionment method nice\, how nice i
s the system we have now\, and can we do better? Don't be too optimistic b
ecause (spoiler) we can't really have nice things. In this talk\, we'll pr
ove why there isn't a "perfect" system of apportionment. If time permits\,
we'll also look at voting systems and discover why we can't have nice thi
ngs there either.\n

DESCRIPTION:Title: How to do math on a supercomputer\nby George Spahn as part of Piz
za Seminar\n\n\nAbstract\nI will talk about my summer internship at Lawren
ce Livermore Lab. Learn how to help physicists make a quantum computer by
solving many differential equations for them! Learn about how to speedup t
he solving of the differential equations by using really really big comput
ers! Learn about my inconsequential results!\n

DESCRIPTION:Title: Introduction to Quantum Computing\nby Jason Saied as part of Pizz
a Seminar\n\n\nAbstract\nThe term "quantum computing" (and\, more generall
y\, anything with the word "quantum" in it) is thrown around a lot by math
ematicians and scientists who want to sound smart. In order to understand
what they were talking about\, I started reading a book about quantum comp
uting. I decided to talk about it at pizza seminar so that you\, too\, cou
ld try to sound smart. I will attempt to explain the postulates of quantum
mechanics and basic notions in quantum computing. We will then discuss th
e speculated strengths of quantum computers\, along with some of the inher
ent difficulties. I will try to address some concepts with fancy-sounding
names that often generate misconceptions\, like quantum teleportation and
the no-cloning theorem. Also\, please note that all of my knowledge is fro
m the first few chapters of Nielsen and Chuang\, so if you already know ab
out quantum computing\, you probably know more than I do.\n

DESCRIPTION:Title: Dirichlet’s theorem + ghosts + a surprise\nby Louis Gaudet as p
art of Pizza Seminar\n\n\nAbstract\nP. G. L. Dirichlet is considered by ma
ny to have created the field of analytic number theory in 1837 when he use
d analytic methods to prove the infinitude of primes in arithmetic progres
sions. I think it’s a fantastic proof---we’ll go through it together\,
and (time permitting) we’ll take a closer look at the remarkable proper
ties of the L-functions involved. (Spoiler alert: these L-functions may be
haunted!) Lastly\, I’ll make sure to take a brief intermission during t
he talk to show you something completely unrelated—I want to share a bit
of how I’ve been “staying sane” during the quarantine...\n

DESCRIPTION:Title: Too acute to be true?\nby Quentin Dubroff as part of Pizza Semina
r\n\n\nAbstract\nIn the late 1940s\, Paul Erdos asked the following innoce
nt-looking question: How many points can one place in R^n such that all an
gles formed by any three are acute? This question was only (mostly) settle
d in the last few years\, and the path to its resolution is marked with a
number of beautiful arguments and surprising twists. I will retell this st
ory\, highlighting some of the most interesting parts. As a bonus\, I will
be giving cute facts\, some real\, some made-up\, and the audience will b
e able to vote on whether the fact is too cute to be true.\n

DESCRIPTION:Title: The Haar measure\nby Leonidas Daskalakis as part of Pizza Seminar
\n\n\nAbstract\nThe focus of this talk is to prove the existence of the Ha
ar measure. The main result is the following: For every locally compact Ha
usdorff topological group there exists a non-trivial left translation-inva
riant measure on the Borel algebra (with even more nice properties which w
e will discuss). That might sound a bit intimidating\, but we will make it
. I will try to include examples and if we have time\, we can discuss conv
olution in this general setting.\n

DESCRIPTION:Title: Playing games smh 🤦\nby James Holland as part of Pizza Seminar
\n\n\nAbstract\nWhat's more fun than playing games? Knowing that they're
pointless! In this talk I will give some examples of games that are deter
mined in that one of the players has a winning strategy. All of this turn
s out to be a part of a larger theory and active program of figuring out w
hat kinds of games are determined and (more importantly) why.\n

DESCRIPTION:Title: The Hairy Ball Theorem\nby Sumeet Khandelwal as part of Pizza Se
minar\n\n\nAbstract\nThe focus of this talk is representation of Clifford
algebra and geometry to show some results for maximum number of independen
t vector field on n-sphere. I will present a simple proof of the "hairy ba
ll theorem" (exact result for 2-sphere)\, which says that a ball cannot be
continuously covered with hairs that are all flattened that uses ideas fr
om algebraic topology. The talk will then cover spinors which are spin rep
resentation of Clifford algebra. Using some basic results in representatio
n theory of Clifford algebras another easy solution will be presented to p
rove the existence of the above number of independent vector field in n-sp
here.\n

DESCRIPTION:Title: The Kissing Number Problem\, Spherical Codes\, and Designs\nby F
orrest Thurman as part of Pizza Seminar\n\n\nAbstract\nWhat's the maximum
number of unit spheres that can touch or "kiss" a given unit sphere withou
t any of them overlapping? This problem is currently only solved in dimens
ions 1\,2\,3\,4\,8\,and 24. We will cover the (surprisingly simple) proof
in dimensions 8 and 24 and what's so special about the optimal configurati
on in these dimensions that makes the proof possible.\n

DESCRIPTION:Title: Model Theory behind Automated Theorem Proving\nby Takehiko Gappo
as part of Pizza Seminar\n\n\nAbstract\nIn 2011\, a Japanese research ins
titute started a project called “Todai Robot Project – Can a Robot Pas
s the University of Tokyo Entrance Exam?” To solve math problems\, their
artificial intelligence heavily relied on an algorithm for quantifier eli
mination for real closed fields\, which was first discovered by Tarski in
1930’s and regarded as one of the earliest theorems in model theory. In
this talk\, I’m going to introduce very basic model theory to explain wh
at Tarski proved and how to use it. Of course\, I’ll talk about the resu
lt of Todai Robot Project too.\n

part of Pizza Seminar\n\n\nAbstract\nI will introduce what is elliptic PD
E and Method of Continuity. And using these materials as a concrete exampl
e\, we will see what we want to prove in the PDE Theory\, for example\, pr
iori estimates. And we will see somehow why estimates are important in PDE
Theory. The talk may include a detailed proof of a functional analysis le
mme which is the base of method of continuity and a detailed application o
f that lemme\, and some big pictures of PDE Theory.\n
