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...

Computational modelling can be used to reveal insights into the mechanisms of new drugs and to develop new diagnostic tools. Here I will discuss three major diseases: diabetes, hypertension, and autism. I will talk about how we construct models to...

In this talk, I will discuss a surprising connection between finite groups of Lie type and string topology of classifying spaces of compact connected Lie groups recently discovered by Jesper Grodal and myself: the cohomology of a finite group of Lie...

The notion of conformal walk dimension serves as a bridge between elliptic and parabolic Harnack inequalities. The importance of this notion is due to the fact that the finiteness of the conformal walk dimension characterizes the elliptic Harnack...

Breast cancer remains the second leading cause of cancer-related death with metastasis accounting around 90% of the total deaths. Specialized subcellular structures termed invadopodia play a critical role in metastasis, aiding tumor cell...

We construct radially symmetric self-similar blow-up profiles for the mass supercritical nonlinear Schrödinger equation with nonlinear exponent close to the mass critical case and for any space dimension. These profiles bifurcate from the ground...

This is the second of a two-part talk. In talk one, I will review various well-known algorithms for integer multiplication, such as schoolbook multiplication, Karatsuba multiplication, FFT multiplication, and the Schoenhage-Strassen algorithm. The...

Error bounds for the conjugate gradient method using minimal polynomials are well known. What are less well known are comparable bounds for indefinite systems using minimal polynomials over two intervals. The key result goes back to Akhieser, with...

Let L/K be a Galois extension of number fields with Galois group G, and let C⊂G be a conjugacy class. Attached to each unramified prime ideal p in OK is the Artin symbol σp, a conjugacy class in G. In 1922 Chebotarev established what is referred to...

Understanding how environmental randomness affects evolution is of fundamental importance for biology. The presence of temporal or spatial randomness significantly affects the competition dynamics in populations and gives rise to some...
