In vector-borne epidemic models there is often a substantial difference between the vector (usually insects) and host (usually humans) time scales. This makes it possible to view the model as a singular perturbation problem and use the quasi-steady...

Integer programming is one of the most fundamental problems in discrete optimization. While integer programming is computationally hard in general, there exist efficient algorithms for special instances. In particular, integer programming is fixed...

Over the past few decades, a lot of attention has been drawn to large-scale streaming data analysis, where researchers are faced with huge amount of high-dimensional data acquired in a stream fashion. In this case, conventional algorithms that...

In this second part of our exposition on the joints problem we showcase Yu and Zhao’s `Joints tightened’. This exciting application of the polynomial method has resulted in a rare occurrence in incidence geometry; the exact constant has been...

What is a game? Mathematically speaking, a game has players, strategies and scores to explain why the players win or lose. Games which are modelled with differential equations are called differential games. Common examples are pursuit-evasion games...

common rules of interaction (chemotaxis), and a biased leakage during the migration can be observed, but it remains unclear how these behaviors are achieved. The traditional Keller-Segel model is successful in modeling chemotactic migration of a...

To a finite group G and an integer q > 0 one can associate the coset-poset of nilpotent subgroups of G of nilpotency class less than q. The nerve of this poset is a simplicial complex denoted E(q,G). It is closely related to a filtration of the...

In classical q-series studies there are examples of eta quotients whose derivatives are also eta quotients. The most famous examples can be found in works of S. Ramanujan and N. Fine. In 2019, in a joint work with P. C. Toh, we have given 203 pairs...
