Non-reciprocal interactions enhance heterogeneity
Timoteo Carletti, Riccardo Muolo
We study a process of pattern formation for a generic model of species anchored to the nodes of a network where local reactions take place, and that experience non-reciprocal long-…
Integrated shape-sensitive functional metrics
Sami Helander, Petra Laketa, Pauliina Ilmonen +3
This paper develops a new integrated ball (pseudo)metric which provides an intermediary between a chosen starting (pseudo)metric d and the L_p distance in general function spaces.…
Adaptive Regularization Minimization Algorithms with Non-Smooth Norms and Euclidean Curvature
Serge Gratton, Philippe L. Toint
A regularization algorithm (AR1pGN) for unconstrained nonlinear minimization is considered, which uses a model consisting of a Taylor expansion of arbitrary degree and regularizati…
Finite propagation enhances Turing patterns in reaction-diffusion networked systems
Timoteo Carletti, Riccardo Muolo
We hereby develop the theory of Turing instability for reaction-diffusion systems defined on complex networks assuming finite propagation. Extending to networked systems the framew…
