Decomposition into subspaces and operator preconditioning: talk by Zdeněk Strakoš

The seminar will take place on Monday, February 19, 2018 at 9:00 am in K4. Prof. Zdeněk Strakoš will present the next part of the lecture “Decomposition into subspaces and operator preconditioning”.

Abstract: We will consider linear equations in the abstract infinite-dimensional Hilbert space setting with bounded, coercive and self-adjoint operators, which can represent, e.g., boundary value problems formulated via partial differential equations.
Efficient numerical solution procedures often incorporate transformation of the original problem using preconditioning. Motivated, in particular, by the works of Faber, Manteuffel, Parter, Oswald, Dahmen, Kunoth and Rude published in the early 90’s, we will present an abstract formulation of operator preconditioning based on the idea of decomposition of a Hilbert space into a finite number of (infinite-dimensional) subspaces, by formulating the main results using the concepts of norm equivalence and spectral equivalence of infinite-dimensional operators. Its goal is to describe in a concise way the common principles behind various adaptive multilevel and domain decomposition techniques using infinite-dimensional function spaces.

An introduction to mathematical homogenization

Stefan Krömer will teach an introductory course on homogenization. If you are interested, please see the details in the attached email.

I am writing to inform you about a small optional course I will be offering in Karlin in the upcoming summer term, “An introduction to mathematical homogenization” for Master or PhD students with a background in Analysis and PDEs:
https://is.cuni.cz/studium/eng/predmety/index.php?do=predmet&kod=NMMO499
The course will be held on Monday, 17:20–18:50 (after the Necas seminar, if possible I will try to move it to ~17:00-18:30, after the first lesson), in a seminar room on the third floor (next to the office of Milan Pokorny, I was told).

As this will be my first course in Karlin, I have to do my best to attract a few students, and I hope you can help me a little with advertising. In particular, please forward this to interested students you might know, or post it somewhere where people can see it.

Anyone interested should feel free to drop me an informal email, I’ll be happy to answer questions:
skroemer@utia.cas.cz

Best regards,
Stefan Krömer

Research Training Group “Interfaces, Complex Structures, and Singular Limits in Continuum Mechanics”

We would like to ask you to inform about the newly established Research Training Group “Interfaces, Complex
Structures, and Singular Limits in Continuum Mechanics” (DFG-Graduiertenkolleg 2339) and the available PhD positions.

Dear colleague,

the newly established Research Training Group “Interfaces, Complex
Structures, and Singular Limits in Continuum Mechanics” (DFG-Graduiertenkolleg 2339)
announces the opening of

11 Doctorate positions

at the Departments of Mathematics of Universitat Regensburg and
of Friedrich-Alexander-Universitat Erlangen-Nuernberg. Seven positions
are starting on April 1, 2018, four positions are starting on
September 1, 2018. The research at the Graduiertenkolleg focuses on
many aspects of advanced mathematical modeling, analysis, and numerics
with the perspective to understand complex phenomena observed in fluid
mechanics, material engineering, biological systems, and other applied
sciences. Typically, interfaces, multiple scales/fields, and small
parameters (singular limits) are core features of the problems to be
studied.

We would like to ask you to inform possible applicants about this
opportunity.

For further information see: http://www.uni-regensburg.de/IntComSin
or contact harald.garcke@ur.de or guenther.gruen@fau.de.
A poster with the announcement of the positions will be send to you by mail.
