Der Workshop "Women in Optimization" findet vom 20. - 22. März 2017 an der Universität Trier statt.  Dieser Workshop richtet sich an Nachwuchswissenschaftlerinnen, Doktorandinnen und Studentinnen der Mathematik mit dem Schwerpunkt Optimierung. Das Ziel des Workshops liegt sowohl in der fachlichen Weiterbildung als auch in der Vernetzung innerhalb der Optimierungscommunity. In Fachvorträgen geladener Referentinnen möchten wir zum einen ein möglichst breites fachliches Spektrum der mathematischen Optimierung und der damit verbundenen Numerik präsentieren. Zum anderen möchten wir den Teilnehmerinnen verschiedene Karrieremodelle…

ALOP Workshop: Stochastic Models and Control

March 22 - March 24
Nells Park Hotel, Dasbachstraße 12
Trier, 54292 Germany

On Wednesday, April 19, 2017,  Dr. Marta D'Elia from the Computer Science Research Institute at Sandia National Laboratories will join the ALOP-Colloquium and present her recent work entitled A coupling strategy for nonlocal and local models with applications to static peridynamics and classical elasticityABSTRACT: The use of nonlocal models in science and engineering applications has been steadily increasing over the past decade. The ability of nonlocal theories to accurately capture effects that are difficult or impossible to represent by local Partial Differential…

On Monday, April 24, 2017,  Prof. Florian Jarre from the Heinrich Heine Universität Düsseldorf will join the ALOP-Colloquium and present his recent work "The Max-Cut-Polytop"AbstractThe max-cut-polytope arises from a simple reformulation of the problem of finding the maximum cut in a graph with given edge weights. Unfortunately, the exact pre-presentation of the cut polytope is not tractable unless NP = Co-NP.We discuss two different representations and inner and outer nonlinear approximations of the max-cut polytope leading to the anticipation that solving…

On Monday, May 15 2017,   Prof. Andreas Frommer of Bergische Universität Wuppertal will join the ALOP-Colloquium and present his recent work entitled Matrix functions - computation and convergence for Krylov subspace based methods Abstract: f(A)b, the action of the function f of a matrix A on a vector b, is required in many applications, for example in exponential integrators, where f = exp or in lattice QCD where f(z) = z-α; α ϵ (0, 1). Typically, A is large and sparse, so…

On Monday, May 29, 2017,  Prof. François Glineur from the Université catholique de Louvain will join the ALOP-Colloquium and present his recent work entitledPerformance estimation of first-order methods for composite convex optimizationComposite convex optimization consists in the minimization of a convex objective function equal to the sum of several convex functions with different properties, for example a smooth term and a nonsmooth term. We consider a large class of first-order methods designed to solve such composite problems, which rely on specific…

On Monday, June 12, 2017,  Prof. Gabriel Wittum of King Abdullah University of Science and Technology  will join the ALOP-Colloquium and present his recent work entitledSimulation of Neuronal Signal ProcessingThe crucial feature of neuronal ensembles is their high complexity and variability. This makes modelling and computation very difficult, in particular for detailed models based on first principles. The problem starts with modelling geometry, which has to extract the essential features from those highly complex and variable phenotypes and at the…
