The Complexity of Subtype Entailment for Simple Types
A subtyping 0 is entailed by a set of subtyping constraints C, written C j= 0, if every valuation (mapping of type variables to ground types) that satisfies C also satisfies 0. ...

A challenge for atomicity verification
An unpublished algorithm of Haldar and Vidyasankar implements an atomic variable of an arbitrary type T for one writer and one reader by means of 4 unsafe variables of type T , th...

Starting SCF calculations by superposition of atomic densities
: We describe the procedure to start an SCF calculation of the general type from a sum of atomic electron densities, as implemented in GAMESS-UK. Although the procedure is well kno...

Omitting types for finite variable fragments and complete representations of algebras
. We give a novel application of algebraic logic to first order logic. A new, flexible construction is presented for representable but not completely representable atomic relation ...
