Mathematical Careers and Ideas is a series of talks offered by the Department of Mathematics for math majors and other undergraduates who have a particular interest in the mathematical sciences.

Here is Professor Buchs's description of his talk:

"Suppose you are given four fixed lines in a three-dimensional space. How many lines can be found which intersect all four given lines? This question is the first interesting problem in enumerative geometry. We will see that its answer does not depend on the choice of fixed lines, as long as they are chosen "at random". On the way to solving the problem we shall
•willfully violate the parallel axiom of Euclidean geometry,
•compute a few small determinants, and
•solve a polynomial equation of degree two."  

Prof. Anders Buch grew up and went to college in Denmark, after which he went to graduate school in Chicago.   He has held positions at MIT and Aarhus University and is now an Associate Professor at Rutgers.

The talk will run from 6:50 to 7:50 p.m.  You are encouraged to arrive at 6:30 for an opportunity to meet other students who are interested in mathematics.
