DESCRIPTION:Title: Ma
thematics of Apportionment\, or Why We Can't Have Nice Things\nby Corr
ine Yap as part of Pizza Seminar\n\n\nAbstract\nHow are the delegates in t
he U.S. House of Representatives assigned? Why does Georgia get 14 while A
labama gets 7? What makes an apportionment method nice\, how nice is the s
ystem we have now\, and can we do better? Don't be too optimistic because
(spoiler) we can't really have nice things. In this talk\, we'll prove 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 things the
re either.\n

many differential equations for them! Learn about how to speedup the solv

DESCRIPTION:Title: In
troduction to Quantum Computing\nby Jason Saied as part of Pizza Semin
ar\n\n\nAbstract\nThe term "quantum computing" (and\, more generally\, any
thing with the word "quantum" in it) is thrown around a lot by mathematici
ans and scientists who want to sound smart. In order to understand what th
ey were talking about\, I started reading a book about quantum computing.
I decided to talk about it at pizza seminar so that you\, too\, could try
to sound smart. I will attempt to explain the postulates of quantum mechan
ics and basic notions in quantum computing. We will then discuss the specu
lated strengths of quantum computers\, along with some of the inherent dif
ficulties. I will try to address some concepts with fancy-sounding names t
hat often generate misconceptions\, like quantum teleportation and the no-
cloning theorem. Also\, please note that all of my knowledge is from the f
irst few chapters of Nielsen and Chuang\, so if you already know about qua
ntum computing\, you probably know more than I do.\n

DESCRIPTION:Title: Di
richlet’s theorem + ghosts + a surprise\nby Louis Gaudet as part of
Pizza Seminar\n\n\nAbstract\nP. G. L. Dirichlet is considered by many to h
ave created the field of analytic number theory in 1837 when he used analy
tic methods to prove the infinitude of primes in arithmetic progressions.
I think it’s a fantastic proof---we’ll go through it together\, and (t
ime permitting) we’ll take a closer look at the remarkable properties of
the L-functions involved. (Spoiler alert: these L-functions may be haunte
d!) Lastly\, I’ll make sure to take a brief intermission during the 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: To
o acute to be true?\nby Quentin Dubroff as part of Pizza Seminar\n\n\n
Abstract\nIn the late 1940s\, Paul Erdos asked the following innocent-look
ing question: How many points can one place in R^n such that all angles fo
rmed by any three are acute? This question was only (mostly) settled in th
e last few years\, and the path to its resolution is marked with a number
of beautiful arguments and surprising twists. I will retell this story\, h
ighlighting some of the most interesting parts. As a bonus\, I will be giv
ing cute facts\, some real\, some made-up\, and the audience will be able
to vote on whether the fact is too cute to be true.\n

DESCRIPTION:Title: Th
e Haar measure\nby Leonidas Daskalakis as part of Pizza Seminar\n\n\nA
bstract\nThe focus of this talk is to prove the existence of the Haar meas
ure. The main result is the following: For every locally compact Hausdorff
topological group there exists a non-trivial left translation-invariant m
easure on the Borel algebra (with even more nice properties which we will
discuss). That might sound a bit intimidating\, but we will make it. I wil
l try to include examples and if we have time\, we can discuss convolution
in this general setting.\n

bstract\nWhat's more fun than playing games? Knowing that they're pointle
ss! In this talk I will give some examples of games that are determined i
n that one of the players has a winning strategy. All of this turns out t
o be a part of a larger theory and active program of figuring out what kin
ds of games are determined and (more importantly) why.\n

DESCRIPTION:Title: T
he Hairy Ball Theorem\nby Sumeet Khandelwal as part of Pizza Seminar\n
\n\nAbstract\nThe focus of this talk is representation of Clifford algebra
and geometry to show some results for maximum number of independent vecto
r field on n-sphere. I will present a simple proof of the "hairy ball theo
rem" (exact result for 2-sphere)\, which says that a ball cannot be contin
uously covered with hairs that are all flattened that uses ideas from alge
braic topology. The talk will then cover spinors which are spin representa
tion of Clifford algebra. Using some basic results in representation theor
y of Clifford algebras another easy solution will be presented to prove th
e existence of the above number of independent vector field in n-sphere.\n

DESCRIPTION:Title: T
he Kissing Number Problem\, Spherical Codes\, and Designs\nby Forrest
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 without any o
f them overlapping? This problem is currently only solved in dimensions 1\
,2\,3\,4\,8\,and 24. We will cover the (surprisingly simple) proof in dime
nsions 8 and 24 and what's so special about the optimal configuration in t
hese dimensions that makes the proof possible.\n

DESCRIPTION:Title: M
odel Theory behind Automated Theorem Proving\nby Takehiko Gappo as par
t of Pizza Seminar\n\n\nAbstract\nIn 2011\, a Japanese research institute
started a project called “Todai Robot Project – Can a Robot Pass the U
niversity of Tokyo Entrance Exam?” To solve math problems\, their artifi
cial intelligence heavily relied on an algorithm for quantifier eliminatio
n 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 ta
lk\, I’m going to introduce very basic model theory to explain what Tars
ki proved and how to use it. Of course\, I’ll talk about the result of T
odai Robot Project too.\n

ethod of Continuity and Linear elliptic PDEs\nby Baozhi Louw as part o
f Pizza Seminar\n\n\nAbstract\nI will introduce what is elliptic PDE and M
ethod of Continuity. And using these materials as a concrete example\, we
will see what we want to prove in the PDE Theory\, for example\, priori es
timates. And we will see somehow why estimates are important in PDE Theory
. The talk may include a detailed proof of a functional analysis lemme whi
ch is the base of method of continuity and a detailed application of that
lemme\, and some big pictures of PDE Theory.\n
