Semigroups for dynamical processes on metric graphs

Kramar Fijavž, Marjeta (author), Puchalska, Aleksandra (author)

We present the operator semigroups approach to the first- and second-order dynamical systems taking place on metric graphs. We briefly survey the existing results and focus on the well-posedness of the problems with standard vertex conditions. Finally, we show two applications to biological models. This article is part of the theme issue "Semigroup applications everywhere".

Abstract

Predstavimo operatorsko polgrupni pristop k dinamičnim sistemom prvega in drugega reda na metričnih grafih. Na kratko strnemo obstoječe rezultate in se osredotočimo na dobro pogojenost problema s standardnimi pogoji v vozliščih. Na koncu prikažemo dve uporabi na modelih v biologiji. Članek je del vsebinske izdaje "Semigroup applications everywhere".
