F eb 2 00 1 Feynman Clocks , Causal Networks , and the Origin of Hierarchical ’ Arrows of Time ’ in Complex Systems

A theory of time as information is outlined using new tools such as Feynman Clocks (FC), Collective Excitation Networks (CENs), and Sequential Excitation Networks (SENs).

F eb 2 00 1 Feynman Clocks , Causal Networks , and the Origin of Hierarchical ’ Arrows of Time ’ in Complex Systems from the Big Bang to the Brain ’

A theory of time as the ’information’ created in the irreversible decay process of excited or unstable states is proposed. Using new tools such as Feynman Clocks (FCs) [1], [2], [3], Feynman Detectors (FDs), Collective Excitation Networks (CENs), Sequential Excitation Networks (SENs), Plateaus of Complexity (POCs), Causal Networks, and Quantum Computation Methods [4], [5], [6] previously separa...

2 F eb 1 99 8 Schrödinger ’ s Interpolation Problem through Feynman - Kac Kernels

We discuss the so-called Schrödinger problem of deducing the microscopic (basically stochastic) evolution that is consistent with given positive boundary probability densities for a process covering a finite fixed time interval. The sought for dynamics may preserve the probability measure or induce its evolution, and is known to be uniquely reproducible, if the Markov property is required. Feyn...

Reduze - Feynman integral reduction in C++

Reduze is a computer program for reducing Feynman integrals to master integrals employing a Laporta algorithm. The program is written in C++ and uses classes provided by the GiNaC library to perform the simplifications of the algebraic prefactors in the system of equations. Reduze offers the possibility to run reductions in parallel. Catalogue identifier: AEGEv10ProgramsummaryURL : http : //cpc...
