Abstract: A sequence of spaces is said to be representation stable if their cohomology, when viewed as representations of their own symmetry, stabilises. Introduced by Church and Farb, representation stability is ubiquitous among various kinds of moduli spaces with permutation symmetry. In this talk I will explain this notion and discuss its appearance in the moduli spaces of flat connections over higher dimensional tori.
