Robin Wilson jest emerytowanym profesorem uniwersytetu w Oxfordzie, Open
University i Gresham College. Pełnił m.in. funkcje prezesa British Society
for the History of Mathematics oraz redaktora naczelnego "European
Mathematical Society Newsletter". Jest autorem lub redaktorem ponad
pięćdziesięciu książek matematycznych, w szczególności "Wprowadzenie
do teorii grafów", "Four Colours Suffice", "Music and mathematics" oraz
dwutomowej monografii "The History of Mathematics: Source-Based Approach" (wydanej przez AMS). Od 1985 roku redaguje "Stamp Corner" w kwartalniku "The Mathematical Intelligencer". Jest laureatem prestiżowych nagród, w tym nagrody Mathematical Association of America za "outstanding expository writing" oraz Medalu Stantona za osiągnięcia w kombinatoryce. Jego liczba Erdősa wynosi 1.


Streszczenia wykładów:


Four Colours Suffice
In this talk I present the history and solution of the four-colour problem: "Can every map be coloured with just four colours so that neighbouring countries are coloured differently?"
The answer is "yes", but the proof took 124 years to find, and used 1200 hours of computer time. But what did it involve, and is it really a proof?



A Century of Graph Theory

This historical talk covers the period from around 1890, when graph theory
was mainly a collection of isolated results, to the 1990s when it had become part of mainstream mathematics. Among many other topics it includes material on the four-colour problem, trees, graph structure, and graph algorithms. No particular knowledge of graph theory is assumed.


Lewis Carroll in Numberland

If Charles Dodgson (Lewis Carroll) hadn't written "Alice's Adventures in
Wonderland" and "Through the Looking-Glass", he would probably be remembered as a pioneer photographer - and also as a mathematician. But what mathematics was he interested in? - and how good was he? In this talk I summarise his mathematical life and works in the context of Victorian
Oxford.
