Let the vertex set
of a graph be partitioned into
parts
, with
. If there is an edge between any two vertices only when they belong to different parts, the graph is called a complete
-partite graph, denoted as
. Let
and
be positive integers,
,
. Consider the complete
-partite graph
.
Answer the following questions:
1. Find the maximum number of disjoint circles (i.e., circles with no common vertices) in this complete
-partite graph.
2. Given
, for all
, find the maximum number of edges in a complete
-partite graph
where no more than one circle is disjoint.
