Random Walk Representations of the Heisenberg Model
In this paper we develop some random walk representations for the spin-S Heisenberg ferromagnet with nearest neighbor interaction on the integer lattice in d dimensions. The representations parallel corresponding representations for the perfect Bose gas. Hence the Heisenberg model can be thought of as an interacting Bose gas. This has been made more explicit in the paper of Dyson (5/ (see also ...
متن کاملA Random Walk in Representations
A RANDOM WALK IN REPRESENTATIONS Shanshan Ding Robin Pemantle The unifying objective of this thesis is to find the mixing time of the Markov chain on Sn formed by applying a random n-cycle to a deck of n cards and following with repeated random transpositions. This process can be viewed as a Markov chain on the partitions of n that starts at (n), making it a natural counterpart to the random tr...
متن کاملMarkov Random Walk Representations with Continuous Distributions
Representations based on random walks can exploit discrete data distributions for cluster ing and classification. We extend such rep resentations from discrete to continuous dis tributions. Transition probabilities are now calculated using a diffusion equation with a diffusion coefficient that inversely depends on the data density. We relate this diffu sion equation to a path integral and d...
متن کاملExemplar-Based Random-Walk Model 1 An Exemplar-Based Random-Walk Model of Categorization and Recognition
Exemplar-Based Random-Walk Model 2 Abstract A fundamental issue in cognitive psychology and cognitive science concerns the manner in which people represent categories in memory and make decisions about category membership. In this chapter we provide a review of a process-oriented mathematical model of categorization known as the exemplar-based random-walk (EBRW) model (Nosofsky & Palmeri, 1997a...
متن کاملthe use of appropriate madm model for ranking the vendors of mci equipments using fuzzy approach
abstract nowadays, the science of decision making has been paid to more attention due to the complexity of the problems of suppliers selection. as known, one of the efficient tools in economic and human resources development is the extension of communication networks in developing countries. so, the proper selection of suppliers of tc equipments is of concern very much. in this study, a ...
