## November 18 is the International Day of LGBTQIA+ People in STEM

November 18 has been selected to celebrate and highlight the work and barriers of LGBTQIA+ people in science, technology, engineering, and maths (STEM). Among their many struggles, we see that 28% of LGBT+ people have at some point considered leaving their jobs because of a hostile workplace or discrimination towards them. 2o% of trans people...

## Job Posting – Instructor I

The Department of Mathematics invites applications for three full-time probationary appointments at the rank of Instructor 1, commencing July 1, 2022, or on a date mutually agreed upon. Mathematics is seeking an emerging scholar with a commitment to excellence in teaching and pedagogical development, including experience teaching in a diverse learning environment. The successful candidate...

## Combinatorics Seminar – Oct 29, 2021

29 October 2021, 2:30pm, Zoom Speaker: Marcelo Sales (Emory)Title: ‘Ramsey and Density Results for Approximate Arithmetic Progressions’ Abstract: Let AP_k = {a,a+d,…,a+(k−1)d} be an arithmetic progression of length k. For a given ε > 0, we call a set AP_k(ε) = {x0,…,xk−1} an ε-approximate arithmetic progression of length k if for some a and d, |xi −(a+id)|<εd...

## Rings and Modules Seminar – Oct. 19

19 October 2021, 2:40 pm, Zoom Speaker: Ranganathan Padmanabhan (University of Manitoba)Title: ‘Hungtington Varieties’ Abstract: A variety KK of lattices is called Huntington if every uniquely complemented lattice in KK is distributive. In 1904, E.V. Huntington conjectured that every uniquely complemented lattice was distributive. In fact, the conjecture had been verified for several special classes of lattices. However, in 1945, Dilworth...

## Combinatorics Seminar – Oct 22, 2021

22 October 2021, 3:30 pm (note the unusual time!), Zoom Speaker: Kyle Murphy (Dakota State)Title: Maximizing Five Cycles in K_r-free Subgraphs Abstract: Recently, Palmer and Gerbner defined the term $F$-Tur\’an Good to describe a graph $H$ which is unique maximized by the Tur\’an graph for all sufficiently large $F$-free graphs. Along with Bernard Lick\’y we...

## Combinatorics Seminar – Oct 15, 2021

15 October 2021, 2:30 pm, Zoom Speaker: Hermie Monterde (Manitoba, Math)Title: Continuous-Time Quantum Walks and Twin Vertices Abstract:Undirected graphs are used to model quantum spin networks, with the vertices and edges representing the qubits and their interactions, respectively. Each of these qubits has an associated quantum state that contains information, and in order to construct an...

## Rings and Modules Seminar – Oct. 5

5 October 2021, 2:40 pm, Zoom Speaker: Raqeeb Rasheed (University of Manitoba)Title: Resultant-Based Methods for Skew Elimination Abstract: This talk is about resultant-based methods for elimination of indeterminates of skew polynomial systems. We define the concept of resultant for bivariate skew polynomials via Dieudonné determinant and then applying a modular technique to improve the efficiency...

## Combinatorics Seminar – Oct 1, 2021

1 October 2021, 2:30 pm, Zoom Speaker: Shahin Kamali (Manitoba, CS)Title: Algorithms for Burning Graph Families Abstract: Graph burning is a simple model for the spread of social influence in networks. The objective is to measure how quickly a “fire”, e.g., a piece of fake news, can be spread in a network. The burning process takes place in...

## Combinatorics Seminar – Sept 24, 2021

24 September 2021, 2:30 pm, Zoom Speaker: Christopher van Bommel (Manitoba, Math)Title: ‘Fidelity of Quantum State Transfer on Paths with Potentials’ Abstract: Quantum computing is believed to provide many advantages over traditional computing, particularly considering the speed at which computations can be performed. One of the challenges that needs to be resolved in order to construct a quantum...

## Welcome Back Coffee

As we ramp back up to full return to campus in January, the Dean, Brian Mark, would like to invite you to have a cup of coffee in the SSA lounge, and weather permitting the Court Yard, to start re-engaging with your colleagues. Please RSVP to Tracy Foster, on the dates noted to ensure we are keeping capacity (20 people) with Health orders. The...
