Probability Seminar: Gordon Slade
November 27, 2019
University of British Columbia
We consider a random walk on the complete graph. The walk experiences competing self-repulsion and self-attraction, as well as a variable length. Variation of the parameters governing the self-attraction and the variable length leads to a rich phase...

A group is said to be torsion-free if it has no elements of finite order. An example is the group, under composition, of self-homeomorphisms (continuous maps with continuous inverses) of the interval I = [0, 1] fixed on the boundary {0, 1}. In fact...

Epithelial cells organize themselves into tubes for the necessary functions of gas and nutrient transport, and the production and secretion of hormones and enzymes. Such tubes result from the organization and collective motion of a flat sheet of...

Scientific Computing, Applied and Industrial Mathematics (SCAIM) Seminar: Ewout van den Berg
November 26, 2019
University of British Columbia
In this talk I will introduce the quantum phase-estimation problem as well as the iterative algorithm by Kitaev that is commonly used to solve it. I show how Kitaev's algorithm can be modified to obtain an asymptotically minimal sampling complexity...

Lethbridge Number Theory and Combinatorics Seminar: Po-Han Hsu
November 25, 2019
University of Lethbridge
Let omega(n) denote the number of distinct prime divisors of n. Let W(m) be a random integer chosen uniformly from the set of natural numbers less than or equal to m. Let X(m) be omega(W(m)). The celebrated Erdos-Kac theorem asserts that if the...

2019 Combinatorial Potlatch
November 23, 2019
Western Washington University, Bellingham
The Combinatorial Potlatch is an irregularly scheduled, floating, one-day conference. It has been held for many years at various locations around Puget Sound and southern British Columbia, and is an opportunity for combinatorialists in the region to...

UW-PIMS Mathematics Colloquium: Rekha Thomas
November 22, 2019
University of Washington
Many results in extremal graph theory can be formulated as inequalities on graph densities. While many inequalities are known,many more are conjectured. A standard tool to establish an inequality is to write the expression whose nonnegativity needs...

UBC Math Department Colloquium: Sookkyung Lim
November 22, 2019
University of British Columbia
Swimming bacteria with helical flagella are self-propelled micro-swimmers in nature, and the swimming strategies of such bacteria vary depending on the number and the position of flagella on the cell body. In this talk, I will introduce two...

BC Data Colloquium Series: Yaser Khalighi
November 21, 2019
Vancouver, BC
There is no shortage of challenges in building self-driving cars and one of the key challenges is the data-availability. In this talk, we will address the challenges in data collection, management, labeling, and validation in the autonomous vehicle...
