The main message in this paper is that there are surprisingly many different Brownian bridges, some of them - familiar, some of them - less familiar. Many of these Brownian bridges are very close to ...

Generalized functions, often formulated as distributions, have become indispensable in the rigorous mathematical formulation of quantum field theory (QFT). These constructs extend the classical notion ...

THE undulatory mechanics makes it possible to give a quantum theory of aperiodic phenomena, and, in particular, to compute the intensity distribution for continuous spectra. The theory has recently ...
