The Van der Waerden Conjecture states that the permanent of a doubly stochastic matrix n x n matrix is at least n!/n^n, which is the case when each entry of the matrix is $1/n$.

Consider the following communication problem. Alice holds a graph $G_A = (P, Q, E_A)$ and Bob holds a graph $G_B = (P, Q, E_B)$, where $|P| = |Q| = n$. Alice is allowed to send Bob a message $m$ that depends only on the graph $G_A$.

In this talk, we will see how certain "degree hardness" properties of a function (e.g approximate degree, sign-degree) amplify to give us "monomial based" hardness properties of a certain "lift" (as defined by Krause and Pudlak (STOC '94)) of the

Suppose $A$ and $B$ are parties in a network and want to communicate with each other privately. This problem is trivial if $A$ and $B$ have a private communication link between them. What if there is no such link?

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.
