Journal of the Australian Mathematical Society - Series A Vol. 64 Part 2 (1998) T-regular probabilistic convergence spaces J. Minkler Department of Mathematics University of Central Florida Orlando, FL 32816-1364 USA e-mail address: garyr@pegasus.cc.ucf.edu and G. Minkler and G. Richardson Abstract: A probabilistic convergence structure assigns a probability that a given filter converges to a given element of the space. The role of the t-norm (triangle norm) in the study of regularity of probabilistic convergence spaces is investigated. Given a probabilistic convergence space, there exists a finest T-regular space which is coarser than the given space, and is referred to as the `T-regular modification'. Moreover, for each probabilistic convergence space, there is a sequence of spaces, indexed by nonnegative ordinals, whose first term is the given space and whose last term is its T-regular modification. The T-regular modification is illustrated in the example involving `convergence with probability $\lambda$' for several t-norms. Suitable function space structures in terms of a given t-norm are also considered. PDF file size: 93K © Copyright 1998, Australian Mathematical Society
