DESCRIPTION:Title: Kneser-Poulsen conjecture: continuous motions\nby Serhii Myrosh
nychenko (UFV) as part of Fraser Valley Math & Stats Seminar\n\nLecture he
ld in C-1425.\n\nAbstract\nThe talk is based on the result by B. Csikos (1
998) who showed that if some balls in the Euclidean space move continuousl
y in such a way that the distances between their centers decrease\, then t
he volume of their union cannot increase. The proof is based on a formula
expressing the derivative of the volume of the union as a linear combinati
on of the derivatives of the distances between the centers with nonnegativ
e coefficients.\n

ummer of 2024. I will go over the basic required notions such as convex bo
dies\, central sections\, support functions\, and a result I proved this s

non-central sections that are supporting lines of an analytic surface in i

DESCRIPTION:Title: The Ubiquity of Smooth Hilbert Schemes\nby Andrew Staal (UFV) a
s part of Fraser Valley Math & Stats Seminar\n\nLecture held in C-1425.\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 properti
es\nof a typical Hilbert scheme? We will discuss Hilbert schemes\nparamet
rizing closed subschemes with a fixed Hilbert polynomial in\nsome projecti
ve space. We will explain how the set of all such\nHilbert schemes forms
a collection of infinite full binary trees.\nExploiting the underlying com
binatorial structure\, we will also see\nhow to classify the Hilbert schem
es containing a unique Borel-fixed\npoint. Viewing the collection of tree
s as a discrete probability\nspace\, we can interpret this as saying that
a random Hilbert scheme is\nsmooth and irreducible with probability greate
r than 0.5.\n

DESCRIPTION:Title: Simulation modelling to inform group O negative red blood cell inv
entory management in British Columbia\nby Jas Dhahan (Simon Fraser Uni
versity) as part of Fraser Valley Math & Stats Seminar\n\nLecture held in
C-1425.\n\nAbstract\nBlood is a crucial life-saving product in healthcare
systems. Red blood cells are perishable\, and managing these stocks in Bri
tish Columbia and other regions of Canada\, with remote / rural hospitals
is challenging. Demand must be satisfied without wasting this resource. Gr
oup O negative red blood cells are a precious resource because they can be
donated universally. O negative individuals comprise 6-7% of our general
population\, yet O negative demand exceeds 12% of transfusions. There is g
rowing concern over the sustainability of the O negative supply. The appro
priate management of even a single red blood cell unit has the potential t
o save a life. \n\nThere are seven health authorities in British Columbia
with over 80 hospitals that manage their own blood inventory. British Colu
mbia is a complex jurisdiction\, which operates a provincial redistributio
n program\, where red blood cells near expiry are sent from smaller to lar
ger sites for use before expiring to minimize wastage.\n\nIn this talk\, w
e discuss our ongoing collaboration with the Provincial Blood Coordination
Office in British Columbia and Canadian Blood Services to inform red bloo
d cell inventory management. We capture the key characteristics of a redis
tribution network of hospital blood banks using a stochastic queue network
model. Our model is calibrated to and validated against real-world data f
rom the Transparent Blood Inventory Database. This work is funded by NSERC
and the Canadian Blood Services Blood Efficiency Accelerator Program.\n

in Trigonometry\nby Glen Van Brummelen (Trinity Western University) a
s part of Fraser Valley Math & Stats Seminar\n\nLecture held in C-1425.\n\
nAbstract\nIn the early 18th century\, Jaipur ruler Jai Singh II gathered
together the intellectual contributions of scientists and mathematicians f
rom across his known world. Among the Sanskrit documents that resulted is
an account from Jagannatha’s Siddhāntakaustubha of the determination of
sin 1° that had occurred in Ulugh Beg’s court in early 15th-century Sa
marqand. The algebraic and iterative methods to find this value\, fundamen
tal to the construction of trigonometric tables and thence to their applic
ation in astronomy\, were inspired by Jamshīd al-Kāshī. Variant methods
from both Samarqand and India are reported in the manuscript. We shall di
scuss these methods and their origins.\n

ir centers decrease\, then the volume of their union cannot increase. Curr
ently this is the only settings where the conjecture has been completely r

statistical models.\nAkaike Information Criterion (AIC) is a metric used t
o measure the quality of a statistical or machine learning model for a giv
en data set.\nWe will use this approach to try and quantify the strength o
f evidence for alternative models.\nFirst we will show a simple model invo
lving High School Basketballers trying to get an athletic scholarship in t
ertiary institutions.
Next\, we will discuss Akaike’s Information Criteria (AIC) and use
it to build parsimonious models related to purchases of used aircrafts.\nW

e useful in building partially ordered sets.\n

DESCRIPTION:Title: Graph Ramsey Games\nby Jane Butterfield (University of Victori
a) 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 t
o avoid a monochromatic thing within a sufficiently large bigger thing. Gr
aph Ramsey theory considers questions like "how many edges can an n-vertex
graph have before it definitely contains a triangle?" In this talk\, we'l
l consdier graph Ramsey games\, which take that basic graph theory questio
n and add a layer of competition to it! Our struggling painter will try de
sperately to avoid monochromatic triangles against an opponent who builds
a graph within various constraints. We'll consider what constraints make t
he game playable for Painter\, and also ask what she should do when playin
g against an entirely random opponent. Along the way we'll see a little bi
t of random graph theory\, but we won't get into any details. If time perm
its\, we'll move from two-colour games into the realm of three-colour game
s. This talk will be accessible to anyone who has played connect-the-dots
before* and is open-minded about what a "triangle" is.\n\n*If you have nev
er played connect-the-dots then some familiarity with graph theory suffice
