Theory of Renormalization and Regularization

Conference held at Hesselberg Academy, 

Hesselberg, Franken (Bavaria)

Evang.-Luth. Volkshochschule Hesselberg, 91726 Gerolfingen

24 February 2002 - 1 March 2002

Organized by E. Vogt (FU Berlin), R. Nest (Univ. Copenhagen), and F. Scheck (Univ. Mainz)

Aims and purpose of the meeting

This conference, organized jointly and attended by a group of mathematicians and theoretical physicists, was part of a continuing series of workshops and conferences held every three years at the Hesselberg Academy. This year's conference was devoted to mathematical aspects of quantum field theory and to topical research in modern quantum field theory. For this reason, some of the lectures are of introductory and pedagogical nature whose aim is to get acquainted with some basic notions and to develop notations and conventions, while others go deep into specific topics of present-day research in quantum field theory.
