Schnyder Woods and Orthogonal Surfaces
In this paper we study connections between planar graphs, Schnyder woods, and orthogonal surfaces. Schnyder woods and the face counting approach have important applications in gra...

Bias matroids with unique graphical representations
Given a 3-connected biased graph with three node-disjoint unbalanced circles, at most one of which is a loop, we describe how the bias matroid of is uniquely represented by .

Complexity of the Satisfiability Problem for a Class of Propositional Schemata
Abstract. Iterated schemata allow to define infinite languages of propositional formulae through formulae patterns. Formally, schemata extend propositional logic with new (generali...

On the Complexity of Partial Order Properties
The recognition complexityof ordered set properties is considered, i.e.how many questions have to be asked to decide if an unknown ordered set has a prescribed property. We prove ...

Morphological wavelets and the complexity of dyadic trees
In this paper we reveal a connection between the coefficients of the morphological wavelet transform and complexity measures of dyadic tree representations of level sets. This le...
