Colloquium more information...
John Lesieutre from Penn State University will be speaking.
The topic of the colloquium is "Polynomial interpolation is harder than it sounds."
This colloquium takes place online.
The description is:
Suppose that (x1,y1),...,(xr,yr) is a set of points in the plane. Given a degree
d and multiplicities mi, does there a nonzero polynomial in two variables of degree at most d which vanishes to order at least mi at(xi,yi)? What is the dimension of the space of such polynomials, and how does it vary with the parameters? I will explain some of the basic results and conjectures and show how this problem is connected to some questions of current interest in algebraic geometry.
