We will study maps on various operator and matrix algebras and their subsets. In particular, we will be interested in maps defined on: -the algebra of real or complex matrices, -matrix algebras over more general fields or division rings, -the set of idempotent matrices, -the set of projections, -finite-dimensional effect algebras, -the space of hermitian matrices, -the space of alternate matrices, -Minkowski space, and on infinite-dimensional analogues of the above sets, for example: -the algebra of all bounded operators on a Hilbert or a Banach space, -effect algebras on Hilbert spaces, -the set of all idempotent operators (projections), -Jordan algebra of all self-adjoint operators. We will assume that these maps are either linear and have some preserving property (in this case we will speak of linear preserver problems), or they have some preserving properties but we do not assume linearity (in this case we will speak of general preserver problems). It is our aim to describe the general form of such maps.
Significance for science
Our research group publishes in international research journals of high quality. The easiest way to prove the relevance of our research to the development of our scientific field is to check the total citations (according to MathSciNet) of leading researchers Peter Šemrl and Matej Brešar. They were cited 2453 times by 764 authors, and 2733 times by 571 authors, respectively. They have an h-index of 20 and 22, respectively.
Significance for the country
