Rajani Singh (Uniwersytet Warszawski (MIM))
A Counterexample --- Discontinuous Nash Equilibria in a Finite Horizon Linear-Quadratic Dynamic Game with Linear Constraints
In this research, we study a simple example of symmetric linear-quadratic dynamic games in which presence of simple linear state dependent constraints results in non-existence of continuous symmetric Nash equilibria and existence of continuum of …

Piotr Bajger (Uniwersytet Warszawski (MIM))
Structure of optimal therapy protocols for a simple compartmental model of chemoresistance
Chemoresistance poses a major obstacle in effective chemotherapy protocol planning. Chemotherapy schedules which prevent or delay the onset of drug resistance are of interest from clinical point of view. This motivated us to formulate an …
Oct. 11, 2017, 2:15 p.m.
Magdalena Bogdańska (Uniwersytet Warszawski (MIM))
Mathematical analysis of the generalised model of chemotherapy of low grade gliomas
We discuss mathematical properties of a generalisation of a model formulated in Bogdańska et al., Math Biosci (2017) that describes evolution of a type of brain tumours, namely low grade gliomas. The proposed model, consisting …

Mariusz Bodzioch (UWM) i Piotr Bajger (MISDMaP) (Uniwersytet Warmińsko-Mazurski/Uniwersytet Warszawski)
Modelling acquired drug resistance in tumours: Effects of mutations and cell competition
Acquired drug resistance is a process during which the cancer cells develop immunity to the chemotherapeutic drug over the course of treatment and poses a major obstacle in effective chemotherapy protocol planning. In 2009 Morno …

Krzysztof Puchta
Dynamic game model of fishery management: a multicohort approach
I will discuss the model of exploitation of southern bluefin tuna presented in Krawczyk and Tołwiński (1993). The aim of the paper was to find a cooperative solution to three-players game between Australia, Japan and …
May 10, 2017, 2:15 p.m.
Urszula Foryś (Uniwersytet Warszawski (MIM))
Mathamatical modelling of dyadic interactions - a case of single meeting
I will present the well-know model of dyadic interaction proposed by Rinaldi et al. to describe romantic relationships. The results will be discussed from a different point of view - a single meeting between persons …
April 26, 2017, 2:15 p.m.
Oskar Górniewicz (doktorant PW)
Verification and refinement of two species Fish Wars model
I will present joint work with Agnieszka Wiszniewska-Matyszkiel: Verification and refinement of two species Fish Wars model. In this paper, we investigate the model of two species Fish Wars model introduced by Fischer and Mirman …
April 5, 2017, 2:15 p.m.
Victor Perez Garcia (Mathematical Oncology Laboratory, Universidad de Castilla-La Mancha)
Mathematics against gliomas: Real-world examples
Mathematical modeling has been used throughly to describe oncological processes in the last decades. However, traslational applications of mathematical models inspired in cancer - the so-called mathematical oncology - are still in their infancy. In …
March 29, 2017, 2:15 p.m.
Lidia Sukovata (Instytut Badawczy Leśnictwa, Zakład Ochrony lasu)
Modelowanie gradacji owadów leśnych w Polsce – stan obecny i problemy badawcze
Najważniejsze pytania w ochronie lasu przed szkodliwymi owadami dotyczą czasu i miejsca, w którym dojdzie do gradacji owadów, tj. wzrostu ich liczebności do poziomu zagrażającego trwałości lasów. W celu uzyskania odpowiedzi na te pytania, wykonuje …
March 22, 2017, 2:15 p.m.
Jacek Banasiak (University of Pretoria)
Analytic fragmentation semigroups and discrete coagulation-fragmentation processes with growth
In the talk we shall describe how the substochastic semigroup theory can be used to prove analyticity of a class of fragmentation semigroup. This result is applied to discrete fragmentation processes with growth to analyze …
March 8, 2017, 2:15 p.m.
Mirosław Lachowicz (Uniwersytet Warszawski (MIM))
Logistic growth at the individual level
I am going to present an individual-based (microscopic) model corresponding to macroscopic logistic growth. The asymptotic stability and ''asymptotic chaos'' will be discussed.
March 1, 2017, 2:30 p.m.
Jan Poleszczuk (IBIB PAN)
Variance-based sensitivity analysis for systems with delays
During the first part of my talk I will make a brief introduction to the variance-based sensitivity analysis methods for general dynamical systems. I will focus mainly on the Fourier Amplitude Sensitivity Test (FAST) which …
Jan. 25, 2017, 2:15 p.m.
Adam Korpusik (Uniwersytet Warszawski/Uniwersytet Warmińsko-Mazurski)
On the nonlocal discretization of basic mathematical models of viral infection
I will present two nonstandard finite difference schemes designed for the numerical simulation of basic mathematical models of viral infection. The proposed methods preserve the non-negativity and equilibria (along with their stability conditions), as well …
Jan. 18, 2017, 2:15 p.m.
Jacek Sadowski (Politechnika Warszawska, Wydział Matematyki i Nauk Informacyjnych)
Differential equations with coeffcients in Sobolev spaces
I would like to talk about ordinary and delay differential equations with coefficients in Sobolev spaces. An example of a differential system with measurable singular right hand side is the system of motion of n-bodies. …
