Three Results on Frequency Assignment in Linear Cellular Networks
In the frequency assignment problem we are given a graph representing a wireless network and a sequence of requests, where each request is associated with a vertex. Each request h...

Rooted Trees Searching for Cocyclic Hadamard Matrices over D4t
A new reduction on the size of the search space for cocyclic Hadamard matrices over dihedral groups D4t is described, in terms of the so called central distribution. This new searc...

There Are Not Non-obvious Cyclic Affine-invariant Codes
We show that an affine-invariant code C of length pm is not permutation equivalent to a cyclic code except in the obvious cases: m = 1 or C is either {0}, the repetition code or it...
