Mathematical Lecture

Mikio Kano
Ibaraki University
Japan
September 15 & 18, 2010

First talk:
Spanning Trees of Graphs (Wednesday, September 15)

ABSTRACT: Some results and problems on spanning trees of graphs will be presented. In particular, we deal with spanning $k$-trees, spanning $k$-ended trees, $k$-leaf connected graphs and others.

Second talk:
Discrete Mathematics with Colored Objects (Saturday, September 18)

ABSTRACT: In a graph coloring, for a given graph, we try to color its vertices or edges so that the resulting colored graph has some given properties. In this talk, we consider the following type of problems. A colored graph with some property is given, then we want to find a some special subgraph (monochromatic, heterochromatic or other kind of subgraph) in it. We consider similar problems on discrete geometry and other discrete mathematics. I think that this type of area will be a big research area in a future.
