Agata Lonc (Szkoła doktorska nauk ścisłych i przyrodniczych UW)
Modelling pathogen spread in a hospital network
In this talk I will present a mathematical framework for modelling pathogen spread across a network of interconnected hospitals. The problem is formulated using two different approaches: an ordinary differential equation model which describes continuous …

Florian Wagener (Amsterdam School of Economics, University of Amsterdam)
Optimal management of weakly interacting natural resources with tipping points
We study the management of natural resources that are weakly connected and exhibit tipping behaviour in their dynamics. We obtain approximate feedback optimal management rules for networks of weakly connected natural resource systems by developing …
Nov. 19, 2025, 2:15 p.m.
Artur Wyciślok (Politechnika Śląska)
Struktury sterowania i wrażliwość wybranych modeli układów biomedycznych
Nov. 12, 2025, 2:15 p.m.
Natalia Bielczyk (Ontology of Value, The Netherlands)
Jak absolwenci uczelni wyższych mogą (a nawet powinni!) odkryć swoją przewagę konkurencyjną i świadomie budować wartość rynkową w karierze zawodowej
Oct. 29, 2025, 2:15 p.m.
Wojciech Misiak (Szkoła doktorska nauk ścisłych i przyrodniczych UW)
Opinion spread: exact and approximate approaches
We introduce an opinion spread model based on evolutionary game theory with players placed on a network and assigned different types. The dynamics are governed by an ergodic Markov chain and we analyse the properties …
Oct. 15, 2025, 2:15 p.m.
Mark Broom (Department of Mathematics, City St.George's, University of London)
Evolutionary models on graphs and structured populations
Evolutionary game theory is used to model how interactions between individuals shape the evolution of populations, and the original, classical works considered infinite populations without structure. When a systematic modelling system based upon structured populations, …
June 4, 2025, 2:15 p.m.
Magdalena Szafrańska-Łęczycka (Szkoła doktorska nauk ścisłych i przyrodniczych UW)
Mathematical modeling of non-standard therapies in neoplastic diseases
We would like to present a comparison of three CAR-T cell therapy approaches for glioblastoma multiforme using mathematical modeling. We extend existing models to investigate the complex dynamics of CAR-T cell therapy in glioblastoma, incorporating …
May 28, 2025, 2:15 p.m.
Jacek Banasiak (University of Pretoria, South Africa/Politechnika Łódzka)
Direct Lyapunov method - known and less known
This will be a continuation of the talk given in March. This time the focus will be on non-smooth Lyapunov functions.
May 7, 2025, 2:15 p.m.
Ana Jacinta Pereira da Costa Soares (University of Minho)
A network model for socio-ecological dynamics
In this seminar, I will present a mathematical model that describes the complex structure of an environmental system, incorporating the influence of the social dynamics on the ecological system. The model consists of a network …

Marcin Penconek
The Theory of Alpha Oscillations in Attractor Networks
Alpha oscillations (8-12 Hz) accompany the awake resting state. However, many experiments suggest the functional relevance of alpha oscillations to a wide range of cognitive processes including attention, working memory, decision-making, and visual consciousness. During …
April 16, 2025, 2:15 p.m.
Akhil Kumar Srivastav (Barcelona Institute of Global Health)
Bifurcation analysis of a two-infection transmission model with explicit vector dynamics
The investigation of epidemiological scenarios characterized by chaotic dynamics is crucial for understanding disease spread and improving control strategies, yet it remains largely unexplored. Motivated by dengue fever epidemiology, we present the SIRSIR-UV model, which …
April 9, 2025, 2:15 p.m.
Łukasz Woźny (SGH)
Interim correlated rationalizability in large games
In this paper we provide general theoretical foundations for modeling strategic uncertainty in large distributional Bayesian games with general type spaces (with aggregate uncertainty) in terms of a version of interim correlated rationalizability. We then …
April 2, 2025, 2:15 p.m.
Bartłomiej Morawski
Neural mass decision-making model with time delay and Hill function
The model of two neuron populations will be investigated, each receiving external signals and influencing each other, which leads to changes in their individual activities. This situation is described using a system of delay differential …
March 26, 2025, 2:15 p.m.
Marcin Choiński (SGGW)
A contiunous-time SIS criss-cross model of co-infection in a heterogeneous population
We introduce and analyze a continuous-time model of co-infection dynamics in a heterogeneous population consisting of two subpopulations that differ in the risk of getting infected by individuals with both diseases. We assume that each …
March 19, 2025, 2:15 p.m.
Mikołaj Rosman (Politechnika Gdańska)
Bistability and chaos in the discrete two-gene Andrecut-Kauffman model
We numerically analyze the dynamics of the two-gene discrete Andrecut-Kauffman model with distinct reaction rates α1 and α2. By exploring bifurcation diagrams and computing the maximum Lyapunov exponent, we identify parameter regions exhibiting chaotic behavior …
