Degree Sequence of a Graph | Graph Theory, Graphical Sequences

What is a degree sequence of a graph? Are graphs with the same degree sequence isomorphic? Do isomorphic graphs have the same degree sequence? We’ll go over all of this in today’s video graph theory lesson! Recall that the degree of a vertex is the number of edges incident to the vertex.

Which Sequences are Graphical? (Degree Sequences and Havel-Hakimi algorithm) | Graph Theory

How do we determine if a sequence is graphical? Remember that a sequence is graphical if it is the degree sequence of some graph. It is of course very easy, given a graph, to find its degree sequence. We just identify the degrees of its vertices then write those degrees in non-increasing o

Graph Theory: 42. Degree Sequences and Graphical Sequences

Here I describe what a degree sequence is and what makes a sequence graphical. Using some examples I'll describe some obvious necessary conditions (which are not sufficient). Then I explain how a Theorem by Havel and Hakimi gives a necessary and sufficient condition for a sequence of non

In this video, we introduce another refinement of THH, the topological periodic homology TP. We see how it is an analogue of HP, how it is related to negative cyclic homology, and how to compute it for the field F_p. Feel free to post comments and questions at our public forum at https:/
