An assistant professor position in mathematical logic, Charles University in Prague, Deadline: 31 October 2014

The Department of Algebra invites applications for a tenure-track position at the rank of assistant professor in the area of mathematical logic. The expected starting date is January 1, 2015 or soon afterwards and is negotiable.

Areas of special interest are:
(i) interactions of logic with computational complexity theory, or
(ii) model theory (any of its facets).
However, strong candidates in all areas of mathematical logic will be considered. Candidates are required to have a proven international research record corresponding to their career stage and a postdoctoral experience.

A successful candidate is expected to pursue an active research program, teach advanced and introductory classes in Czech and/or English and possibly supervise undergraduate and graduate students. Teaching in Czech is not required. (English is sufficient since the advanced classes may be taught in English even in standard undergraduate programs.)

The expected duration of the initial contract is three years. Such a position is renewable under a mutual agreement for another three years (and possibly for further three years, depending on the career stage). These new contracts depend on how successfully the assistant professor carries out research and teaching duties. Then, subject to a separate review process (called a habilitation), a promotion to the rank of associate professor is usual. This promotion is usually connected with a tenure. However, if the candidate’s career is already advanced with a strong research record, the initial period can be substantially reduced and you can progress to the promotion very fast.

Electronic applications accompanied by:

a curriculum vitae
a proof of PhD in a relevant field
a list of publications
a description of pedagogical experience

should be sent to Mrs. Eva Ramesova at ramesova@karlin.mff.cuni.cz.
The candidate should also arrange for two letters of recommendation to be sent directly to the same address. Informal inquiries are welcome and may be sent to Prof. Jan Krajicek at krajicek@karlin.mff.cuni.cz.
The application deadline is October 31, 2014.

Early applications are encouraged; applications may be processed as they are received.

We may invite the best candidates for an interview during October – mid November; after that the final round of selection will follow.

Yair Hayut: Stationary reflection at successors of singulars

Forcing seminar (Tel Aviv University)
Yair Hayut will speak this Tuesday (8/7/14)
(9:10-11, Schreiber 209) his abstract :
Stationary reflection at successors of singulars
I will show how to get, starting with ω supercompact cardinals, a model in which every stationary set at some specific, predefined, successor of singular reflects. This is a simplification of results of Shelah and Magidor for the 80′s and 90′s. The reflection properties obtained this way are indestructible by closed enough forcing, so we can separate some combinatorical properties this way.  For this end, I define the approachability property and show its relations to preservation of stationary sets under closed forcing notions.
If time permits, I’ll show how to obtain Shelah’s model, in which every stationary set that can reflect reflects in the same way.

Christopher Eagle: Model theory of abelian real rank zero C*-algebras

27 June 2014, 13:30–15:00

Fields institute, Room 210

Speaker: Christopher Eagle

Title: Model theory of abelian real rank zero C*-algebras

Abstract: We consider algebras of the form $C(X)$, where $X$ is a $0$-dimensional compact Hausdorff space, from the point of view of continuous model theory.  We characterize these algebras up to elementary equivalence in terms of invariants of the Boolean algebra $CL(X)$ of clopen subsets of $X$.  We also describe several saturation properties that $C(X)$ may have, and relate these to topological properties of $X$ and saturation of $CL(X)$.  We will discuss some consequences of saturation when we view $C(X)$ as a $C^*$-algebra.  All the necessary background on continuous logic will be provided. This is joint work with Alessandro Vignati.

Otmar Spinas: “Das Problem mit Silver Amoeba”

Monday, June 23, 2014, 16.30
Seminar room 0.011, Mathematical Institute, University of Bonn

Speaker: Otmar Spinas (Kiel)

Title: “Das Problem mit Silver Amoeba”

Abstract:

Ich werde die offene Frage eroertern, ob ein Amoeba für Silver-Forcing existiert, das keine Cohen reelle Zahlen adjungiert. In der Sprache der kardinalen Invarianten ist dies die Frage, ob konsistenterweise die Ueberdeckungszahl des mageren Ideals kleiner als die Additivitaet des Silver-Ideals ist.
