Symmetry reduction of a model in spherical symmetry for benign tumor

Risultato della ricerca: Other

Abstract

A PDEs system, describing the expansive growth of a benign tumor and the phe-nomenon of encapsulation, is studied via a group analysis approach. A weak equiv-alence classi¯cation is obtained and the original PDEs system is reduced to anODEs system. Numerical simulations are performed both for ODEs and PDEs,which turn out to be in perfect agreement between each other, showing a realisticenough description of the biological process.
