Davis (2003) discussed non-uniqueness and solvability conditions of two types of infinite systems that occur in various biharmonic boundary-value problems for a rectangular domain studied by Meleshko ...

In this paper we apply a family of heuristics to solve the rectangle layout problem. Our principal technique, however, is a variant of local optimization. This technique, which we call sacrificing, ...

In mid-March, the mathematicians Joshua Greene and Andrew Lobb found themselves in the same situation: locked down and struggling to adjust while the COVID-19 pandemic grew outside their doors. They ...
