DESCRIPTION:Title: Kneser-Poulsen conjecture: continuous motions\nby Serhii
Myroshnychenko (UFV) as part of Fraser Valley Math & Stats Seminar\n\nLec
ture held in C-1425.\n\nAbstract\nThe talk is based on the result by B. Cs
ikos (1998) who showed that if some balls in the Euclidean space move cont
inuously in such a way that the distances between their centers decrease\,
then the volume of their union cannot increase. The proof is based on a f
ormula expressing the derivative of the volume of the union as a linear co
mbination of the derivatives of the distances between the centers with non
negative coefficients.\n

n the summer of 2024. I will go over the basic required notions such as co

this summer which shows that a convex polygon can be uniquely determined
by the non-central sections that are supporting lines of an analytic surfa

DESCRIPTION:Title: The Ubiquity of Smooth Hilbert Schemes\nby Andrew Staal
(UFV) as part of Fraser Valley Math & Stats Seminar\n\nLecture held in C-1
425.\n\nAbstract\nIn this talk\, I will try to give a gentle introduction
to the Hilbert scheme. A motivating question is: What are the geometric p
roperties\nof a typical Hilbert scheme? We will discuss Hilbert schemes\n
parametrizing closed subschemes with a fixed Hilbert polynomial in\nsome p
rojective space. We will explain how the set of all such\nHilbert schemes
forms a collection of infinite full binary trees.\nExploiting the underly
ing combinatorial structure\, we will also see\nhow to classify the Hilber
t schemes containing a unique Borel-fixed\npoint. Viewing the collection
of trees as a discrete probability\nspace\, we can interpret this as sayin
g that a random Hilbert scheme is\nsmooth and irreducible with probability
greater than 0.5.\n

DESCRIPTION:Title: Simulation modelling to inform group O negative red blood c
ell inventory management in British Columbia\nby Jas Dhahan (Simon Fra
ser University) as part of Fraser Valley Math & Stats Seminar\n\nLecture h
eld in C-1425.\n\nAbstract\nBlood is a crucial life-saving product in heal
thcare systems. Red blood cells are perishable\, and managing these stocks
in British Columbia and other regions of Canada\, with remote / rural hos
pitals is challenging. Demand must be satisfied without wasting this resou
rce. Group O negative red blood cells are a precious resource because they
can be donated universally. O negative individuals comprise 6-7% of our g
eneral population\, yet O negative demand exceeds 12% of transfusions. The
re is growing concern over the sustainability of the O negative supply. Th
e appropriate management of even a single red blood cell unit has the pote
ntial to save a life. \n\nThere are seven health authorities in British Co
lumbia with over 80 hospitals that manage their own blood inventory. Briti
sh Columbia is a complex jurisdiction\, which operates a provincial redist
ribution program\, where red blood cells near expiry are sent from smaller
to larger sites for use before expiring to minimize wastage.\n\nIn this t
alk\, we discuss our ongoing collaboration with the Provincial Blood Coord
ination Office in British Columbia and Canadian Blood Services to inform r
ed blood cell inventory management. We capture the key characteristics of
a redistribution network of hospital blood banks using a stochastic queue
network model. Our model is calibrated to and validated against real-world
data from the Transparent Blood Inventory Database. This work is funded b
y NSERC and the Canadian Blood Services Blood Efficiency Accelerator Progr
am.\n

425.\n\nAbstract\nIn the early 18th century\, Jaipur ruler Jai Singh II ga
thered together the intellectual contributions of scientists and mathemati
cians from across his known world. Among the Sanskrit documents that resul
ted is an account from Jagannatha’s Siddhāntakaustubha of the determina
tion of sin 1° that had occurred in Ulugh Beg’s court in early 15th-cen
tury Samarqand. The algebraic and iterative methods to find this value\, f
undamental to the construction of trigonometric tables and thence to their
application in astronomy\, were inspired by Jamshīd al-Kāshī. Variant
methods from both Samarqand and India are reported in the manuscript. We s
hall discuss these methods and their origins.\n

-invariant functionals on \\(\\mathbb{R}^2\\)\, we will progress to explor
e the more intricate structures arising in Banach spaces. The presentation
will focus on showcasing examples of group invariant functionals\, operat
ors\, and multilinear mappings\, highlighting the geometric insights they
provide. We will also discuss the techniques used to study these mappings
and investigate how classical functional analysis results translate into t

DESCRIPTION:Title: How Statistics Protects Privacy\nby Vahid Tadayon (UFV)
as part of Fraser Valley Math & Stats Seminar\n\nLecture held in D-122B.\
n\nAbstract\nModern society generates vast amounts of data through everyda
y activities such as online interactions\, financial transactions\, mobili
ty patterns\, and health records. While analyzing these data can produce v
aluable insights that improve decision-making in many areas\, it also rais
es serious concerns about individual privacy. Even datasets that appear an
onymized can often be linked with other sources to re-identify individuals
. In this talk\, we focus on differential privacy\, a framework that prote
cts individual information by incorporating carefully calibrated randomnes
s into data analysis. Although differential privacy is not a new concept\,
the rapid advancement of machine learning technologies has made it an inc
reasingly important tool across many disciplines. We introduce the key ide
as behind this approach and illustrate how privacy protection influences s
tatistical accuracy and inference.\n

DESCRIPTION:Title: Graph Ramsey Games\nby Jane Butterfield (University of
Victoria) as part of Fraser Valley Math & Stats Seminar\n\nLecture held in
C-1425.\n\nAbstract\nAbstract: Ramsey theory is all about how impossible
it is to avoid a monochromatic thing within a sufficiently large bigger th
ing. Graph Ramsey theory considers questions like "how many edges can an n
-vertex graph have before it definitely contains a triangle?" In this talk
\, we'll consdier graph Ramsey games\, which take that basic graph theory
question and add a layer of competition to it! Our struggling painter will
try desperately to avoid monochromatic triangles against an opponent who
builds a graph within various constraints. We'll consider what constraints
make the game playable for Painter\, and also ask what she should do when
playing against an entirely random opponent. Along the way we'll see a li
ttle bit of random graph theory\, but we won't get into any details. If ti
me permits\, we'll move from two-colour games into the realm of three-colo
ur games. This talk will be accessible to anyone who has played connect-th
e-dots before* and is open-minded about what a "triangle" is.\n\n*If you h
ave never played connect-the-dots then some familiarity with graph theory
suffices.\n
