DESCRIPTION:Speaker: Noema Nicolussi\nhosted by Jan Maas\nAbstract: There a
re two different notions of a Laplacian operator associated with infinite
graphs: discrete Laplacians and quantum graphs. Both objects have a venera
ble history and their spectral theory relates to several diverse branches
of mathematics (random walks\, combinatorics\, geometric group theory\, ..
.). In our talk we explore connections between these two types of operator
s (spectral\, parabolic and geometric properties)\, and exploit these rela
tions to prove a number of new results in spectral theory for both setting
s. The talk is based on joint work with Aleksey Kostenko (Ljubljana&Vienna
) and Mark Malamud (Donetsk).
