Jan Hubička: Combinatorial proofs of the extension property for partial automorphisms

Dear all, The seminar meets on Wednesday February 13th at 11:00 in the Institute of Mathematics CAS, Zitna 25, seminar room, 3rd floor, front building. Program: Jan Hubička — Combinatorial proofs of the extension property for partial automorphisms Class K of finite structures has extension property for partial automorphisms (EPPA) if for every A in K there exists B in K such that every partial automorphism of A (that is isomorphism of two substructures of A) extends to automorphism of B. continue reading…
