Adjacent vertex distinguishing total chromatic number of graph products

Amitayu Banerjee, Jayabalan Geetha, Kanagasabapathi Somasundaram

The adjacent vertex distinguishing (AVD)-total chromatic number of a graph is the least integer for which has a proper total coloring with colors s…

AVD Total Colorings of Subdivision Graphs, Joins, and Deleted Lexicographic Products

Amitayu Banerjee

In 2020, Panda, Verma, and Keerti asked whether the central graph of every graph satisfies the AVD-total coloring conjecture. In this paper, we verify the conjecture for central gr…

Automorphism Groups and Structure of 4-Valent Cayley Graphs on Dihedral Groups

Amitayu Banerjee

Let be a finite group and let be an inverse-closed subset of not containing the identity. The Cayley graph has vertex set , where two vertices $x…

The List-distinguishing chromatic number of graphs containing only small complete bigraphs

Amitayu Banerjee

In 2006, Collins and Trenk obtained a general sharp upper bound for the distinguishing chromatic number of a connected graph. Inspired by Catlin's combinatorial techniques from 197…

Automorphism groups and Distinguishing Colorings of Central and Middle Graphs

Amitayu Banerjee, Alexa Gopaulsingh, Zalán Molnár

Let G be a simple, finite, connected, and undirected graph. The middle graph M(G) of G is obtained from the subdivision graph S(G) after joining pairs of subdivided vertices that l…

On the Cost Number of Graphs with Determining Number Two

Alexa Gopaulsingh, Zalán Molnár, Amitayu Banerjee

A distinguishing vertex coloring of a graph is a vertex coloring such that only the identity automorphism of preserves the coloring. A graph is -distinguishable if it ad…

Distinguishing chromatic number of middle and subdivision graphs

Amitayu Banerjee, Alexa Gopaulsingh, Zalán Molnár

Let be a simple finite connected graph of order greater than or equal to . We obtain the following results: (1). We apply a result of Hamada and Yoshimura from 1976 and…

Brooks' type theorems for coloring parameters of locally finite graphs and Konig's Lemma

Amitayu Banerjee, Zalán Molnár, Alexa Gopaulsingh

In the past, analogues to Brooks' theorem have been found for various parameters of graph coloring for infinite locally finite connected graphs in ZFC. We prove these theorems are…

Upper bounds for the list-distinguishing chromatic number

Amitayu Banerjee, Zalán Molnár, Alexa Gopaulsingh

We prove analogs of Brooks' Theorem for the list-distinguishing chromatic number of different classes of simple finite connected graphs. Moreover, we determine two upper bounds for…

Distinguishing colorings, proper colorings, and covering properties without the Axiom of Choice

Amitayu Banerjee, Zalán Molnár, Alexa Gopaulsingh

We work with simple graphs in ZF (Zermelo--Fraenkel set theory without the Axiom of Choice (AC)) and assume that the sets of colors can be either well-orderable or non-well-orderab…
