Polynomial families of incident flags and explicit off-diagonal Ramsey graphs

Brecht Verbeken, Brecht F. Verbeken

We construct explicit off-diagonal Ramsey graphs from polynomial families of incident point--hyperplane flags. Universal interpolation translates the exact dimension of ordered cli…

The Eigenvalue Region of a Family of Markov Chains with Randomness Confined to Two States

Brecht Verbeken, Brecht F. Verbeken, Vincent Ginis

We determine the complete eigenvalue region of the following Markov chains on $2 q$ states, for $q \geq 2$ . The states are $A_{0}, \dots, A_{q - 1}$ and $B_{0}, \dots, B_{q - 1}$ . Each transitio…
