Beyond Bayesian Inference: The Correlation Integral Likelihood Framework and Gradient Flow Methods for Deterministic Sampling

Piotr Gwiazda, Alexey Kazarnikov, Anna Marciniak-Czochra +1

Calibrating mathematical models of biological processes is essential for achieving predictive accuracy and gaining mechanistic insight. However, this task remains challenging due t…

Stochastic parabolic equations in Musielak-Orlicz spaces with discontinuous in time N-function

Piotr Gwiazda, Jakub Woźnicki, Aneta Wróblewska-Kamińska +1

We consider a stochastic parabolic partial differential equation with Dirichlet boundary conditions, multiplicative stochastic noise, and a monotone parabolic operator A. The growt…

Lipschitz stability for Bayesian inference in porous medium tissue growth models

Tomasz Dębiec, Piotr Gwiazda, Błażej Miasojedow +3

We consider a macroscopic model for the dynamics of living tissues incorporating pressure-driven dispersal and pressure-modulated proliferation. Given a power-law constitutive rela…

Rigorous derivation of magneto-Oberbeck-Boussinesq approximation with non-local temperature term

Piotr Gwiazda, Florian Oschmann, Aneta Wróblewska-Kamińska

We consider a general compressible, viscous, heat and magnetically conducting fluid described by the compressible Navier-Stokes-Fourier system coupled with induction equation. In p…

Operator splitting algorithm for structured population models on metric spaces

Carolin Lindow, Christian Düll, Piotr Gwiazda +2

In this paper, we propose a numerical scheme for structured population models defined on a separable and complete metric space. In particular, we consider a generalized version of…
