Dear GMS, I hope you all had a productive reading week. If you didn't, don't worry: here is a picture to make your day better. [cid:80ccea49-2a00-4d5f-910d-306231dfbc63] You are welcome. We will have a seminar on 19th of November, Wednesday in 123 St. Paul's between 12:30 and 13:30. Our speaker is @Solomon Mensah<mailto:mensahs2@myumanitoba.ca>. The details about his talk are below. Title: A single patch and Climate-Based Metapopulation Malaria Model with Human Travel and Treatment Abstract: In this talk, we present single-patch and metapopulation models for malaria transmission that incorporate human movement between regions with varying climatic conditions, the use of effective and counterfeit treatments, and time-periodic parameters for mosquito dynamics. We develop an algorithm to compute the threshold condition $R_0$ for epidemiological systems derived from compartmental deterministic models. The analysis shows that when $R_0<1$, the disease-free equilibrium (DFE) is locally asymptotically stable, while $R_0>1$ leads to instability of the DFE. Under additional reasonable assumptions, we establish conditions under which the DFE is globally asymptotically stable, showing that, in many cases, this occurs precisely when $R_0≤1$.

Dear GMS, I wish this message find you well. We will have a seminar on 5th of November, Wednesday in 123 St. Paul's between 12:30 and 13:30. Our speaker is @Joshua Beaudin<mailto:beaudin3@myumanitoba.ca>. The details about his talk are below. Title: Development and Application of t-Distributed Stochastic Neighbourhood Embeddings Abstract: t-Distributed Stochastic Neighbourhood Embedding (tSNE) is a technique developed in the past couple decades which has become a commonly employed data visualization tool for statisticians. The main problem of focus is on how to map high-dimensional data into two or three dimensions such that the distribution of how the transformed data is clustered is as close as possible to its original high-dimensional distribution. tSNE is a technique aimed at addressing this problem. This talk will focus on building up the relevant theory for the derivation of the technique complete with some applications of it. The seminar can also be accessed from Zoom: https://umanitoba.zoom.us/j/61904749902?pwd=NBzY0WN8ItdlMq2fZiKCpb1uPf8L8i.1 Meeting ID: 619 0474 9902 Passcode: 846191 See you all in the seminar!

Dear GMS, I hope you're all doing well! We will have a seminar on 22th of October, Wednesday in 123 St. Paul's between 12:30 and 13:30. Our speaker is @Marshall Kaatz<mailto:kaatzm1@myumanitoba.ca>. The details about his talk are below. Title: Building the foundations for a new Ramsey-type problem Abstract: Ramsey numbers have gained notoriety over the last century for the difficulty of computing exact values or even improving known bounds, and have given rise to a large family of Ramsey-type problems. The classical theorem of Ramsey can be rephrased in terms of independent sets: in large enough graphs, either the graph or its complement will have a large independent set. In this talk, I present a natural analogous problem to that of the classical Ramsey numbers. Observing that an independent set is a special case of an acyclic set in a graph — that is, a set of vertices which induces no cycles — we instead study how in large enough graphs, either the graph or its complement will have a large acyclic set. In addition to presenting key theorems and constructions, I will discuss some small non-trivial exact values and best-known bounds. The seminar can also be accessed from Zoom: https://umanitoba.zoom.us/j/61904749902?pwd=NBzY0WN8ItdlMq2fZiKCpb1uPf8L8i.1 Meeting ID: 619 0474 9902 Passcode: 846191 See you all in the seminar!

Dear all, This is a gentle reminder that we have a seminar today in 123 St. Paul's between 12:30 and 13:30. Our speaker is Jaskaran Kaire. You can find more information about his talk in the previous email. Pizza will be served today. See you all there! Sincerely, Berkant<https://cnnk.xyz> GMS Executive ________________________________ From: Berkant Cunnuk <cunnukb(a)myumanitoba.ca> Sent: Monday, October 6, 2025 5:13 PM To: um-gms(a)lists.umanitoba.ca <um-gms(a)lists.umanitoba.ca> Subject: Grad Seminar on October 8, Wednesday Dear GMS, I hope this message finds you well! Our second seminar will take place on 8th of October, Wednesday in 123 St. Paul's between 12:30 and 13:30. Our speaker is Jaskaran Kaire. The details about his talk are below. Title: Illumination number of cap bodies in small dimensions Abstract: Despite recent progress on the Illumination conjecture, it remains open in general, as well as for specific classes of bodies. Bezdek, Ivanov, and Strachan showed that the conjecture holds for symmetric cap bodies (a specific class of convex bodies) in sufficiently high dimensions. Further, Ivanov and Strachan calculated the illumination number for the class of 3-dimensional centrally symmetric cap bodies to be 6. In this talk/presentation, I will show that even the broader class of all 3-dimensional cap bodies has the same illumination number 6. In addition, I will show that the conjecture also holds for any n-dimensional cap bodies, where 3 < n < 20. The proof is based on probabilistic arguments and integer linear programming. This talk is based on joint work with A. Arman and A. Prymak. The seminar can also be accessed from Zoom: https://umanitoba.zoom.us/j/61904749902?pwd=NBzY0WN8ItdlMq2fZiKCpb1uPf8L8i.1 Meeting ID: 619 0474 9902 Passcode: 846191 We will be serving pizza this week.
