Introduction to Magic Labelings of Graphs II
Talk on the DiMaS seminar.
Abstract
Magic type labeling are an analogue to magic squares well known from recreational mathematics.
First we introduce various magic type graph labelings:
 a vertex magic total (VMT) labeling of a graph G(V,E),
 an (s,d)vertex antimagic total (VAMT) labeling,
 a supermagic (SPM) labeling (also known as vertex magic edge labeling).
In the beginning we review the definitions and some examples.
This talk should introduce the notion of magic rectangles and especially Kotzig arrays.
These arrays are used to construct magic type labelings of regular graphs, copies of regular graphs or products of regular graphs.
In the talk we present recent results post some research problems realted to the MacDougall's conjecture that any regular graph with the exception of K_{2} and 2K_{3} has a VMT labeling.
