Discrete Laplacians on the hyperbolic space -- a compared study

The main motivation behind this paper stems from a notable gap in the existing literature: the absence of a discrete counterpart to the Laplace-Beltrami operator on Riemannian manifolds, which can be effectively used to solve PDEs. We consider that t

Asymptotic-preserving finite difference method for partially dissipative hyperbolic systems

Autor: Crin-Barat, Timothée, Manea, Dragoş

In this paper, we analyze the preservation of asymptotic properties of partially dissipative hyperbolic systems when switching to a discrete setting. We prove that one of the simplest consistent and unconditionally stable numerical methods - the cent

A Payne-Whitham model of urban traffic networks in the presence of traffic lights and its application to traffic optimisation

Autor: van Dissel, Mauritz Cartier, Gora, Paweł, Manea, Dragoş

Urban road transport is a major civilisational and economic challenge, affecting the quality of life and economic activity. Addressing these challenges requires a multidisciplinary approach and sustainable urban planning strategies to mitigate the ne

Concentration limit for non-local dissipative convection-diffusion kernels on the hyperbolic space

Autor: González, María del Mar, Ignat, Liviu I., Manea, Dragoş, Moroianu, Sergiu

We study a non-local evolution equation on the hyperbolic space $\mathbb{H}^N$. We first consider a model for particle transport governed by a non-local interaction kernel defined on the tangent bundle and invariant under the geodesic flow. We study

The Hardy inequality and large time behaviour of the heat equation on $\mathbb{R}^{N-k}\times (0,\infty)^k$

Autor: Cazacu, Cristian, Ignat, Liviu I., Manea, Dragoş

In this paper we study the large time asymptotic behaviour of the heat equation with Hardy inverse-square potential on corner spaces $\mathbb{R}^{N-k}\times (0,\infty)^k$, $k\geq 0$. We first show a new improved Hardy-Poincar\'{e} inequality for the
