The Liars Game is a turn-based two-player game (lets call the two players Alice and Bob). The game is specified by two positive integers $k$ and $n$ which are known to both Alice and Bob.

The usual idea of compactness of a space is that if the space has an open cover then it has a finite subcover which is not very intuitive. In this talk we attempt to look at some equivalent characterisations of compact spaces.

Linear sketch complexity of a Boolean function f on a set of n inputs, introduced by Kannan, Mossel and Yaroslavtsev, is, in informal terms, the smallest integer d such that the value of the function can be concluded with high probability from the
