Workshop on Partial Differential Equations,

Calais, May 16, 2018,

on the occasion of the retirement of our colleague Joachim von Below.


12:30   Lunch.

14:00   J. A. Lubary (Universitat Polytècnica de Catalunya, Barcelona): Eigenvalue multiplicities for the Laplacian on metric graphs.

14:50   I. Wood (University of Kent, Canterbury): A functional model for maximally dissipative operators.

Abstract: We introduce an abstract framework for a maximally dissipative operator A and its anti-dissipative adjoint and use this framework to construct the selfadjoint dilation of A using the Straus characteristic function. The advantage of this construction is that the parameters arising in the dilation are explicitly given in terms of parameters of A (such as coefficients of a differential expression). The abstract theory will be illustrated by the example of dissipative Schrodinger operators.

15:40   Coffee break.

16:10   D. Mugnolo (FernUniversität in Hagen): Can one hear the shape of a network? - Twenty years after.

17:00   S. Nicaise (Université de Valenciennes et du Hainaut-Cambrésis): Dynamical boundary/interface conditions on ramified spaces.

Where will the conference take place?

The conference will take place in Calais, in room B014 on the campus "la Mi-Voix" of the Université du Littoral.

This room is located in the ground floor of the building connected to the low, round, red-brick tower on the campus (see below). When you enter this tower, B014 is the first room on the right-hand side.
