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.
