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? Weβll go over all of this in todayβs video graph theory lesson! Recall that the degree of a vertex is the number of edges incident to the vertex.

What is an arithmetic sequence
π Learn about sequences. A sequence is a list of numbers/values exhibiting a defined pattern. A number/value in a sequence is called a term of the sequence. There are many types of sequence, among which are: arithmetic and geometric sequence. An arithmetic sequence is a sequence in which

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
