A Simple Stochastic Game is a game with a reachability objective played by two players on a directed graph. Each vertex of the graph is either controlled by one of the players or is a probabilistic vertex.

Can a sender encode a pair of messages (m0, m1) jointly, and send their encoding over (say) a binary erasure channel, so that the receiver can decode exactly one of the two messages and the sender does not know which one?

How does one store a graph in the database? Typically the vertices are labelled by a set {1, 2, ..., n}. The edges can be denoted in many different ways: adjacency matrix, incidence matrix, adjacency list, to name a few.

We give a new proof of the fact that the parallel repetition of the (3-player) GHZ game reduces the value of the game to zero polynomially quickly.

We know that for matrices A and B, AB is not the same as BA in general. But suppose B is a polynomial in A, like B = A^2 - 3A + I (note I = A^0). Then AB is indeed the same as BA.

Tiling of a surface is acted upon by its automorphism group. The tilings with single vertex orbit, the transitive tilings, are well studied since antiquity.
