NPCW04 - Approximation, deformation, quasification A finitely generated group G is be called TESTABLE ( or stable w.r.t. to the symmetric groups) if every almost homomorphism from G into a symmetric group Sym(n) is “close” to a real homomorphism. In the talk (which is a first in a series of two; the second will be given by Oren Becker), we will present this notion, its relation to local testability in computer science and its connections with other group theoretic concepts such as sofic groups, amenability, residual finiteness, the profinite topology, LERF and Kazhdan's property (T).
