Topic:

An association scheme for twin prime powers

Description:

Twin prime powers are used in the construction of some very interesting combinatorial objects. In an old paper they are used in the construction of regular Hadamard matrices. In a recent work, they are used to show the existence of an infinite class of Hadamard matrices lacking a certain algebraic structure.

In this talk I will discuss the use of twin prime powers in order to show the existence of a class of translation commutative association schemes. I will use the twin primes 3 and 5, as an example, to make the talk accessible to everyone.
