The Morgan Prize Committee is pleased to award honorable mention for the 2003 Morgan Prize to Karen Yeats for a series of outstanding contributions on topics ranging from asymptotics and number theory to mathematical logic. A few examples indicate the broad versatility of her research.

One of Karen Yeats' research projects is motivated by a precise analogy between results in additive number theory and results in multiplicative number theory. Based on this analogy, Karen Yeats has proved a multiplicative version for Dirichlet series of a classical estimate of Schur on the size of the coeffients of a product of two power series.
