A ug 2 00 1 To the finite information content of the physically existing reality Wolfgang Orthuber

Every physical measuring needs a finite, different from zero measurement time and provides information in form of the choice of a measurement result from all possible measurement results. If infinitely many (different) measurement results would be possible, the choice of a measurement result could deliver an infinite quantity of information. But the results of physical measurings (of finite dur...

A discrete and finite approach to past physical reality

This paper is a synthesis of previously published material on the topic. We show that an adequate mathematical model for the physical (i.e., perceptible and therefore past) reality must be finite. A finite approach to past proper time is given. Proper time turns out to be proportional to the sum of the return probabilities of a Bernoulli random walk. 1. Introduction. Every physical measurement ...

We develop the Wigner phase space representation of a kicked particle for an arbitrary but periodic kicking potential. We use this formalism to illustrate quantum resonances and anti–resonances.

We compute CH∗BG2 and CH ∗(BSpin7)(2), using in particular the stratification method introduced by Vezzosi. We also give some information on the Chow rings of the finite groups G2(q). This is a preliminary draft. I will add at least a few comments on higher spin groups.
