This volume
presents a collection of papers covering applications from a wide range of
systems with infinitely many degrees of freedom studied using techniques from
stochastic and infinite dimensional analysis, e.g. Feynman path integrals, the
statistical mechanics of polymer chains, complex networks, and quantum field
theory. Systems of infinitely many degrees of freedom create their particular
mathematical challenges which have been addressed by different mathematical
theories, namely in the theories of stochastic processes, Malliavin calculus,
and especially white noise analysis.

These
proceedings are inspired by a conference held on the occasion of Prof. Ludwig
Streit’s 75th birthday and celebrate his pioneering and ongoing work in these
fields.
