Maximal Neighborhood Search and Rigid Interval Graphs
A rigid interval graph is an interval graph which has only one clique tree. In 2009, Panda and Das show that all connected unit interval graphs are rigid interval graphs.

Coloring problem of signed interval graphs [PDF]
A signed graph $(G,\sigma)$ is a graph together with an assignment of signs $\{+,-\}$ to its edges where $\sigma$ is the subset of its negative edges.

The interval thickness of a graph G is the minimum clique number of all the interval supergraphs of G. The clique number of a graph is the number of nodes of its biggest complete subgraph. On the other hand, the node- search number is the least number of searchers (pebbles) required to clear the ''contaminated'' edges of a graph. A contaminated edge is

Strong Interval – Valued Pythagorean Fuzzy Soft Graphs
A Strong interval – valued Pythagorean fuzzy soft sets (SIVPFSS) an extending the theory of Interval-valued Pythagorean fuzzy soft set (IVPFSS). Then we Propose Strong interval valued Pythagorean fuzzy soft graphs (SIVPFSGs).

We study domination between different types of walks connecting two non-adjacent vertices u and v of a graph (shortest paths, induced paths, paths, tolled walks).

Open-interval graphs versus closed-interval graphs
It is proved that a countable graph is a closed-interval graph if and only if it is an open-interval graph. A counter-example is given for uncountable graphs. Also the case of unit length intervals is studied.

- and -labeling problems on interval graphs
For a given graph , the - and -labeling problems assign the labels to the vertices of . Let be the set of non-negative integers. An - and -labeling of a graph is a function such that , for respectively, where represents the distance (minimum number of ...

3D-interval-filament graphs [PDF]
Gavril [F. Gavril, Maximum weight independent sets and cliques in intersection graphs of filaments, Inform. Process. Lett. 73 (2000) 181–188] defined two new families of intersection graphs: the interval-filament graphs and the subtree-filament graphs ...

Tractabilities and Intractabilities on Geometric Intersection Graphs
A graph is said to be an intersection graph if there is a set of objects such that each vertex corresponds to an object and two vertices are adjacent if and only if the corresponding objects have a nonempty intersection.
