This survey is concerned with structural characteristics ofsuns' in normed linear spaces, with
special emphasis on connectedness and monotone path-connectedness. Consideration is …

The uniqueness of this book lies in describing generalized metric spaces by means of
map**s. Back in 1961, Alexandroff [3] proposed the idea of using the map** method to …

In this paper, we define soft ω-open sets and strongly soft ω-open sets as two new classes of
soft sets. We study the natural properties of these types of soft sets and we study the validity …

It is the aim of this chapter to introduce the reader to the theory of quasi-uniform spaces.
Besides discussing various bitopological aspects of that theory, we treat the important …

In this paper, we study the graph classification problem from the graph homomorphism
perspective. We consider the homomorphisms from $ F $ to $ G $, where $ G $ is a graph of …

In this paper a graph of the discrete topology under some conditions has been created. It is
obtained from the composition of the topologies. The properties and domination number on …

Dominating sets play an important role in applications of graph theory. Recent studies in this
field studied properties of minimum dominating sets (γ-set). The other type of studies …

Previous research has dealt with the topic of topological graph in several aspects and has
studied the set of vertices or set of edges as a sub basis for topological space. The topic of …

We use the recently established existence and regularity of area and energy minimizing
disks in metric spaces to obtain canonical parameterizations of metric surfaces. Our …
