Dynamical Sampling in Graph Paley--Wiener Spaces
Iulia Martina Bulai, Carlos Cabrelli, Elena Cordero +2
We study dynamical sampling for graph signals using the spectral theory of the normalized graph Laplacian. Graph Paley-Wiener spaces GPW_w are defined as spectral subspaces associa…
Optimization of the total tumor population under Gompertz growth
Iulia Martina Bulai, Francesca Gladiali, Benedetta Pellacci
We study optimal control problems for a stationary reaction--diffusion model describing the spatial distribution of a tumor cell population with Gompertz growth. The control …
Beyond Single-Window Graph Fourier Analysis
Iulia Martina Bulai, Elena Cordero, Edoardo Pucci +1
We introduce a multi-windowed graph Fourier transform (MWGFT) for the joint vertex-frequency analysis of signals defined on graphs. Building on generalized translation and modulati…
A geometric analysis of the SIRS compartmental model with fast information and misinformation spreading
Iulia Martina Bulai, Mattia Sensi, Sara Sottile
We propose a novel slow-fast SIRS compartmental model with demography, by coupling a slow disease spreading model and a fast information and misinformation spreading model. Beside…
Comparing disease control policies for interacting wild populations
Iulia Martina Bulai, Roberto Cavoretto, Bruna Chialva +2
We consider interacting population systems of predator-prey type, presenting four models of control strategies for epidemics among the prey. In particular to contain the transmissi…
