Complexity dichotomy on partial grid recognition
Deciding whether a graph can be embedded in a grid using only unitlength edges is NP-complete, even when restricted to binary trees. However, it is not difficult to devise a numbe...

Primitive words and roots of words
In the algebraic theory of codes and formal languages, the set Q of all primitive words over some alphabet Σ has received special interest. With this survey article we give an ove...

Planar Graph Coloring Avoiding Monochromatic Subgraphs: Trees and Paths Make It Difficult
We consider the problem of coloring a planar graph with the minimum number of colors so that each color class avoids one or more forbidden graphs as subgraphs. We perform a detail...

Avoiding Deontic Explosion by Contextually Restricting Aggregation
Abstract. In this paper, we present an adaptive logic for deontic conflicts, called P2.1r , that is based on Goble’s logic SDLaPe—a bimodal extension of Goble’s logic P that...

Low PAPR STBCs from Complex Partial-Orthogonal Designs (CPODs)
— Space-time codes from complex orthogonal designs (CODs) with no zero entries offer low Peak to Average power ratio (PAPR) and avoid the problem of turning off antennas. But COD...
