The role of indirect prey-taxis and interference among predators in pattern formation
It is important to find biological factors that may lead to formation of patches in the distribution of species. We build a simple model describing a consumer/predator which, besides random dispersion, searches for food by …

The big unknown: The asymptomatic spread of COVID-19
This talk draws attention to the asymptomatic and mildly symptomatic cases of COVID-19, which, according to some reports, may constitute a large fraction of the infected individuals. These cases are often unreported and are not …

Automated data collection from bitmap images on Polish Health Ministry's Twitter. Some thoughts on COVID-19 statistics in Poland.
I will only briefly focus on the technicalities. Polish Ministry of Health publishes a large part of the coronavirus-related data only in the form of bitmap images on Twitter. I wrote a set of Python …

Evolutionary analysis and modeling of coronavirus genomes
Studies have shown that novel coronavirus (SARS-CoV-2) causing coronavirus disease 2019 (COVID-19) most likely was transmitted to humans by animal carriers. It is therefore interesting to ask how the virus has evolved in organisms of …

Error estimation in the Runge-Kutta method for systems of ODEs
Sometimes we are not able to provide analytical proof for some properties of the model. In such a case we need to carry out numerical simulations and give a rigorous argument in order to prove …

Using real data for construction of a dynamical model to personalize androgen deprivation therapy in hormone-sensitive prostate cancer
The results of cooperation with IMBM team on modeling of HSCP treated with leuprolide will be presented. We proposed a new mechanistic model describing cancer growth represented by a level of prostate specific antigen in …

Mathematics of a COVID Pandemic or How to Throw Stones at the Infection Curve
The role of mathematicians in helping to understand the dynamics of the 2020 pandemic and to offer useful insights seems by now hard to deny. In that spirit, I will present some recent work that …

Markov evolution of infinite age-structured populations of migrants (Ewolucja nieskończonych populacji migrantów ze strukturą wiekową)
In this talk, I would like to present the Markov evolution of infinite age-structured populations of migrants arriving in and departing from a continuous habitat at random and independently of each other. Each population member …

Impact of the constant and time-varied contact rate on COVID-19 pandemic dynamic
We constructed a simple Susceptible-Infected-Infectious-Excluded model of the spread of COVID-19. The model is parametrized only by the average incubation period \tau and two rate parameters: contact rate, r_C, and exclusion rate, r_E. The rates …

Jacek Banasiak (UniversitRenormalization group and Chapman-Enskog methods in singularly perturbed dynamical systems on [0,∞)
Recently there have appeared several papers discussing applications of the so-called renormalization group method in singularly perturbed systems of equations. In this talk, I shall show that somewhat forgotten Chapman-Enskog asymptotic method leads to the …

On the Tikhonov-type theorem for a certain class of singularly perturbed differential inclusions
We are going to compare some of recent results of Tikhonov type devoted to singularly perturbed differential inclusions. The object of investigation is the lower- and the upper-semicontinuity of the set of solutions of the …
