Efficient implementation of adaptive order reconstructions
Matteo Semplice, Giuseppe Visconti
Including polynomials with small degree and stencil when designing very high order reconstructions is surely beneficial for their non oscillatory properties, but may bring loss of…

A level-set multigrid technique for nonlinear diffusion in the numerical simulation of marble degradation under chemical pollutants
Armando Coco, Matteo Semplice, Stefano Serra-Capizzano
Having in mind the modelling of marble degradation under chemical pollutants, e.g.~the sulfation process, we consider governing nonlinear diffusion equations and their numerical ap…
