Lower bounds for sumsets of multisets in Z_p^2

Greg Martin, Alexis Peilloux, Erick B. Wong

The classical Cauchy-Davenport theorem implies the lower bound n+1 for the number of distinct subsums that can be formed from a sequence of n elements of the cyclic group Z_p (when…

The number of 2x2 integer matrices having a prescribed integer eigenvalue

Greg Martin, Erick B. Wong

Random matrices arise in many mathematical contexts, and it is natural to ask about the properties that such matrices satisfy. If we choose a matrix with integer entries at random,…

Almost all integer matrices have no integer eigenvalues

Greg Martin, Erick B. Wong

For a fixed $n \geq 2$ , consider an $n \times n$ matrix $M$ whose entries are random integers bounded by $k$ in absolute value. In this paper, we examine the probability that $M$ is si…
