Mathematisches Forschungsinstitut Oberwolfach Mini-workshop: Wellposedness and Controllability of Evolution Equations

چکیده
Fast control cost for heat-like semigroups: Lebeau-Robbiano strategy and Hautus test Luc Miller (joint work with Thomas Duykaerts) Since the seminal work of Russell and Weiss in [7], resolvent conditions for various notions of admissibility, observability and controllability, and for various notions of linear evolution equations have been studied intensively, sometimes under the name of infinite-dimensional Hautus test, cf. [8, 2]. This talk based on [1] investigates resolvent conditions for null-controllability in arbitrary time: necessary conditions for general semigroups, and sufficient conditions for analytic normal semigroups and semigroups with negative self-adjoint generators.

The Algebraic Stat ist ics of an Oberwolfach Workshop
From the 17th to the 22nd of April 2017, a Workshop on Algebraic Statistics took place at the Mathematisches Forschungsinstitut Oberwolfach (MFO). The weather started off cold with intermittent rain showers. The middle of the week saw snow and hail, and there were two sunny days at the end. Many of the 52 workshop participants were visiting Oberwolfach for the first time, and some of them playe...
متن کاملNumerical solution of optimal control problems for descriptor systems
We discuss optimal control problems for general unstructured linear differentialalgebraic equations of arbitrary index. We discuss controllability and observability in the higher order case and show that order reduction may lead to false results. We then derive necessary conditions in the case of linear-quadratic control problems and show how these lead to eigenvalue problems for for even matri...

Enumerative Combinatorics focusses on the exact and asymptotic counting of combinatorial objects. It is strongly connected to the probabilistic analysis of large combinatorial structures and has fruitful connections to several disciplines, including statistical physics, algebraic combinatorics, graph theory and computer science. This workshop brought together experts from all these various fiel...
متن کاملMathematisches Forschungsinstitut Oberwolfach Mini-workshop: Combinatorics on Words
The area of combinatorics on words is concerned with properties of sequences of symbols. It is characteristic to the field that questions arise from various mathematical problems, and hence, many fundamental results on words have been established in different areas. Over the last two decades the theory has developed into a quickly growing topic of its own. This workshop was dedicated to reflect...
