Baire-one mappings contained in a usco map
We investigate Baire-one functions whose graph is contained in a graph of usco mapping. We prove in particular that such a function defined on a metric space with values in R^d is the pointwise limit of a sequence of contin...

On dynamics of graph maps with zero topological entropy
We explore the dynamics of graph maps with zero topological entropy. It is shown that a continuous map f on a topological graph G has zero topological entropy disjointness conjecture is true for graph ...

Cycle-continuous mappings - order structure
Given two graphs, a mapping between their edge-sets is cycle-continuous, and Raspaud, we prove that there exists an infinite set of graphs with no cycle-continuous mapping between them. Further extending this resul...

Automatic data classification based on the triangular graph for thematic maps
A triangular point graph helps in the process of data classification for a thematic map. A triangular graph can be used for a situation that is described by three graph. The typology of the situation can be subsequ...

Hanani-Tutte for approximating maps of graphs
We resolve in the affirmative conjectures of A. Skopenkov and Repovš (1998), and M. Skopenkov (2003) generalizing the classical Hanani-Tutte theorem to the setting of approximating maps of graphs on 2-dimensional surfaces by embeddi...

Cycle-Continuous Mappings-Order Structure
Given two graphs, a mapping between their edge-sets is cycle-continuous conjecture that for every bridgeless graph there is a cycle-continuous mapping to the Petersen graph, which, if solved positively, wo...

Omega-limit sets and distributional chaos on graphs
We give a full topological characterization of omega limit sets of continuous maps on graphs and we show that basic sets have similar properties as in the case of the compact interval. We also prove that the presence of distribution...

Homomorphisms between graphs embedded in surfaces
We extend the notion of graph homomorphism to cellularly embedded graphs (maps obtain the first definition of map homomorphism that preserves both the combinatorial structure (as a graph homomorphism) and ...
