Наслов предавања: Polyhedra on hyperboloids

Садржај:

A spherical cat ate too much, a Euclidean cat took too many risks on the road, while a hyperbolic cat needed to be fed. In the talk, their cat houses will be specified: a fat cat fits in any regular polyhedron, while a flat cat can be nicely covered by tessellations, but what about the hungry cat? Here, we need ‘hyperbolic polyhedra’: they do not fit on a sphere, but on a hyperboloid. They could interest the creative geometric minds: while almost everything seems to have been said about regular polyhedra, polyhedra with vertices on a hyperboloid still need to be discovered. The talk will propose some examples, but the list surely will not be exhaustive. And so, perhaps some dreamy mathematician will one day elaborate a hyperbolic cosmic Mysterium for comets with a hyperbolic trajectory, equivalent to Kepler’s Mysterium for the planets with their elliptic orbits.

Note: no cats will be hurt during the talk.

Биографија предавача:

Dirk Huylebrouck obtained his Ph.D. in linear algebra from the University of Ghent, Belgium, in 1986. He spent 9 years in Congo, until an official diplomatic incident interrupted his stay. This propelled him to Portugal and to the European Division of Maryland University, until his American (military) students went to Iraq. He returned to Africa, to Burundi, but only for 3 years, because of the genocide in neighboring Rwanda. Since 1996, he has taught in the Department of Architecture Sint-Lucas, Brussels-Ghent, Belgium. He has edited the column “The Mathematical Tourist” in “The Mathematical Intelligencer”, since 1997. In 2002 he won the “Lester Ford Award” for best mathematical paper in “The American Mathematical Monthly”. He probably is better known for his re-discovery of the Ishango rods (the oldest mathematical objects), for organizing the first clockwise 400m, or for having revealed errors in the mathematics of Leonardo da Vinci, in the Brussels’ Atomium, in a Fibonacci artwork in Belgium, or in a painting of Eva’s forbidden fruit&хеллип;.
