Extended Walk-on-Spheres Algorithm for Linear and Nonlinear Elliptic Problems of Divergence-type

Iulian Cîmpean, Andreea Grecu, Arghir Zarnescu

The Walk-on-Spheres algorithm, introduced by M. E. Muller in 1956, is a well known Monte Carlo method that leverages Brownian exit distributions from spheres to solve the Laplace e…

A probabilistic approach to spectral analysis of Cauchy-type inverse problems: Convergence and stability analysis

Iulian Cîmpean, Andreea Grecu, Liviu Marin

A comprehensive convergence and stability analysis of some probabilistic numerical methods designed to solve Cauchy-type inverse problems is performed in this study. Such inverse p…

Hardy uniqueness principle for the linear Schrodinger equation on quantum regular trees

Aingeru Fernández-Bertolin, Andreea Grecu, Liviu I. Ignat

In this paper we consider the linear Schrodinger equation (LSE) on a regular tree with the last generation of edges of infinite length and analyze some unique continuation properti…

The nonlinear Schrödinger equation with white noise dispersion on quantum graphs

Iulian Cîmpean, Andreea Grecu

We show that the nonlinear Schrödinger equation (NLSE) with white noise dispersion on quantum graphs is globally well-posed in once the free deterministic Schrödinger group s…

The Schrodinger Equation on a Star-Shaped Graph under General Coupling Conditions

Andreea Grecu, Liviu I. Ignat

We investigate dispersive and Strichartz estimates for the Schrödinger time evolution propagator on a star-shaped metric graph. The linear operator, $H…
