Welcome to my homepage ! I am absolutely delighted we can meet online. I am member of the Mathematics Institute of the Universität zu Köln. I am also member of the Institute of Mathematics of the Romanian Academy (IMAR). My field of interest lies between Complex Geometry, Global Analyis and Spectral Theory.
Please consult my list of papers and preprints.
Recurrent themes are the topics of the book Holomorphic
Morse inequalities and Bergman kernels by Xiaonan Ma and myself.
This book was awarded the 2006 Ferran Sunyer i Balaguer Prize.
I was awarded the 2014 Simion Stoilow prize of the Romanian Academy.
Watch a talk by Paul Wiegmann at Simons Center on our work with Semyon Klevtsov and Xiaonan Ma about Quantum Hall effect.
Survey (with pictures) on zeros of random polynomials (joint with Turgay Bayraktar, Dan Coman and Hendrik Herrmann).
By the way, speaking about administration,
Thou shalt not do as the dean pleases, Thou shalt not answer questionnaires
Thou shalt not write thy doctor's thesis Or quizzes upon World-Affairs,
On education, Nor with compliance
Thou shalt not worship projects nor Take any test. Thou shalt not sit
Shalt thou or thine bow down before With statisticians nor commit
Administration. A social science
Thou shalt not be on friendly terms Thou shalt not live within thy means
With guys in advertising firms, Nor on plain water and raw greens.
Nor speak with such If thou must choose
As read the Bible for its prose, Between the chances, choose the odd;
Nor, above all, make love to those Read The New Yorker, trust in God;
Who wash too much. And take short views.
