Codes with a Certain Weight-preserving Transitive Group of Automorphisms
We determine all linear codes C containing the constant code E, for which there is a weight-preserving group of semilinear automorphisms which acts transitively on the set of nont...

Generalized Quadrangles with an Abelian Singer Group
In this note we characterize thick finite generalized quadrangles constructed from a generalized hyperoval as those admitting an abelian Singer group, i.e., an abelian group actin...

Access control in a core calculus of dependency
The Dependency Core Calculus (DCC) is an extension of the computational lambda calculus that was designed in order to capture the notion of dependency that arises in information-f...

Self-Reciprocal Irreducible Pentanomials Over F2
Joseph Yucas and Gary Mullen conjectured that there is no self-reciprocal irreducible pentanomial of degree n over F2 if n is divisible by 6. In this note we prove this conjecture ...

Faster Algorithm for Designing Optimal Prefix-Free Codes with Unequal Letter Costs
Abstract. We address the problem of designing optimal prefix-free codes over an encoding alphabet with unequal integer letter costs. The most efficient algorithm proposed so far ha...
