Benjamini-Schramm limit of the heat semigroup on quantum graphs

Mihály Kovács, Eszter Sikolya

We study the behaviour of heat semigroups on quantum graphs under Benjamini-Schramm convergence. For quantum graphs with uniformly bounded geometry, equipped with continuity and Ki…

Journey Through the World of Dynamical Systems on Networks

A. Puchalska, M. N. Cartier van Dissel, P. Gora +9

We present a subjective selection of methods for complex systems analysis ranging from statistical tools through numerical methods based on AI to both linear and non-linear ODEs an…

On the strong Feller property of the heat equation on quantum graphs with Kirchoff noise

Mohamed Fkirine, Mihály Kovács, Eszter Sikolya

We consider a so-called quantum graph with standard continuity and Kirchhoff vertex conditions where the Kirchhoff vertex condition is perturbed by Gaussian noise. We show that the…

Reaction-diffusion equations on metric graphs with edge noise

Eszter Sikolya

We investigate stochastic reaction-diffusion equations on finite metric graphs. On each edge in the graph a multiplicative cylindrical Gaussian noise driven reaction-diffusion equa…

On the parabolic Cauchy problem for quantum graphs with vertex noise

Mihály Kovács, Eszter Sikolya

We investigate the parabolic Cauchy problem associated with quantum graphs including Lipschitz or polynomial type nonlinearities and additive Gaussian noise perturbed vertex condit…

Stochastic reaction-diffusion equations on networks

Mihály Kovács, Eszter Sikolya

We consider stochastic reaction-diffusion equations on a finite network represented by a finite graph. On each edge in the graph a multiplicative cylindrical Gaussian noise driven…

On the stochastic Allen-Cahn equation on networks with multiplicative noise

Mihály Kovács, Eszter Sikolya

We consider a system of stochastic Allen-Cahn equations on a finite network represented by a finite graph. On each edge in the graph a multiplicative Gaussian noise driven stochast…

Ornstein-Uhlenbeck approximation of one-step processes: a differential equation approach

Peter L. Simon, Eszter Sikolya

The steady state of the Fokker-Planck equation corresponding to a density dependent one-step process is approximated by a suitable normal distribution. Starting from the master equ…

Semigroups of max-plus linear operators

Marjeta Kramar Fijavž, Aljoša Peperko, Eszter Sikolya

We define strongly continuous max-additive and max-plus linear operator semigroups and study their main properties. We present some important examples of such semigroups coming fro…

Variational and Semigroup Methods for Waves and Diffusion in Networks

Marjeta Kramar Fijavz, Delio Mugnolo, and Eszter Sikolya

We study diffusion and wave equations in networks. Combining semigroup and variational methods we obtain well-posedness and many nice properties of the solutions in general L^p -co…

Differential equation approximations of stochastic network processes: an operator semigroup approach

András Bátkai, Istvan Z. Kiss, Eszter Sikolya +1

The rigorous linking of exact stochastic models to mean-field approximations is studied. Starting from the differential equation point of view the stochastic model is identified by…

The norm convergence of a Magnus expansion method

András Bátkai, Eszter Sikolya

We consider numerical approximation to the solution of non-autonomous evolution equations. The order of convergence of the simplest possible Magnus method will be investigated.
