George Marinescu


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.

Short CV


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.
Hermetic Decalogue from "Under Which Lyre (A Reactionary Tract for the Times)" by 
W.H. Auden (1946)
