Description: Preservers Everywhere is an international conference on the dynamically developing topic commonly referred to as "Preserver Problems". A preserver is a transformation between mathematical structures that leaves a certain quantity/operation/relation/set etc. invariant. The usual goal is to give a complete description of these transformations. Typical examples include homomorphisms of groups (i.e. maps which respect group operations) and isometries of metric spaces (i.e. maps preserving distances). The purpose of this meeting is to bring together mathematicians from various areas who are either working on or interested in such problems. Amongst others, we will have talks on preserver problems related to Algebra, Analysis, Functional Analysis, Geometry, Linear Algebra, Mathematical Physics and Operator Theory. We encourage everybody interested in this topic to participate the meeting. 

The venue is the Bolyai Institute of the University of Szeged, whose past members include F. Riesz, B. Kerékjártó, A. Haar, T. Radó, and L. Kalmár, who can be seen in the following famous picture taken in 1928.
