Each fall, the Purdue University Department of Mathematics and College of Science recognize outstanding Purdue alumni. Alex Himonas, Professor of Mathematics at the University of Notre Dame, is the 2009 Outstanding Mathematics Alumnus.
Himonas received his Ph.D. in Mathematics in 1985 under the direction of Salah Baouendi. Himonas is interested in the regularity of solutions to linear partial differential equations (PDE), and in the Cauchy problem for nonlinear evolution equations. His earlier work concentrated on the microlocal analytic regularity of the solutions to principal type PDE with analytic coefficients. More recently, he is working on the regularity theory (analytic, smooth) for degenerate elliptic PDE, in particular PDE that are sums of squares of vector fields. In non-linear PDE, he is working on the well-posedness of the initial value problem for evolution equations.
Himonas will give a talk at Purdue University on Thursday, September 24 at 4:30 p.m. in BRNG 1230. There will be a dinner following the talk in honor of Prof. Himonas and other outstanding alumni of the Department of Statistics and the Actuarial Science program. On Friday afternoon, Purdue University will host a reception for their outstanding alumni.
