Abstract

In this paper, we study partitions of totally positive integral elements α\alpha in a real quadratic field KK. We prove that for a fixed integer m1m \geq 1, an element with mm partition exists in almost all KK. We also obtain an upper bound for the norm of α\alpha that can be represented as a sum of indecomposables in at most mm ways, completely characterize the α\alpha's represented in exactly 22 ways, and subsequently apply this result to complete the search for fields containing an element with mm partitions for 1m71 \leq m \leq 7.
