Representations of partially ordered sets in unitary spaces
(recent results and open problems).
Abstract:
The representation theory of partially ordered sets
(posets) in linear vector
spaces has been studied extensively and found to be of great
importance for studying different algebraical objects. We try to
develop similar theory over unitary spaces. Direct transfer of the
definitions leads to *-wild problems almost from the beginning.
Hence we consider those representations that satisfy extra conditions
(motivation to study such representations comes from certain moduli
problems). The aim of the talk is to give a survey of recent results
and open problems concerning to this topic.
