23th Hyogo Science E-cafe "Universality and Applications of Mathematics: a sojourn into graph theory"
Crossing Bridges:
In Konigsberg (present-day Kaliningrad), whether you can walk in the city by crossing each of the 7 bridges exactly once was a famous riddle. For his negative solution of this riddle, the Swiss mathematician Leonhard Euler introduced the notion of graphs. We will talk about the mathematics around this notion and some of its interesting theories and applications (Sakae Fuchino).
History of coloring maps with four colors:
The 4-color mapping problem became popular only after a supposed proof was found to have an error, at the end of the 19th century. At the time, it was thought that the error would be easy to fix, but, in the process of finding out that this is not so, the problem grew in fame. In this talk we will dip a bit into the graph theory underlying this story (Wayne Rossman).
