Bundle Theory of Improper Spin Transformations
We first give a geometrical description of the action of the parity operator (P̂ ) on non relativistic spin 12 Pauli spinors in terms of bundle theory. The relevant bundle, SU(2)⊙Z2 → O(3), is a non trivial extension of the universal covering group SU(2) → SO(3). P̂ is the non relativistic limit of the corresponding Dirac matrix operator P = iγ0 and obeys P̂ 2 = −1. Then, from the direct product o...
متن کاملTransformations of infinitely divisible distributions via improper stochastic integrals
Let X(ds) be an R-valued homogeneous independently scattered random measure over R having μ as the distribution of X ((t, t+1]). Let f(s) be a nonrandom measurable function on an open interval (a, b) where −∞ 6 a < b 6 ∞. The improper stochastic integral ∫ b− a+ f(s)X(ds) is studied. Its distribution Φf (μ) defines a mapping from μ to an infinitely divisible distribution on R. Three modificatio...
متن کاملA Study on Properties of Dempster-Shafer Theory to Probability Theory transformations
In this paper, five conditions that have been proposed by Cobb and Shenoy are studied for nine different mappings from the Dempster-Shafer theory to the probability theory. After comparing these mappings, one of the considerable results indicates that none of the mappings satisfies the condition of invariance with respect to the marginalization process. In more details, the main reason for this...
متن کاملMereological bundle theory
Bundle theory takes objects to be bundles of properties. Some bundle theorists take objects to be bundles of instantiated universals, and some take objects to be bundles of tropes. Tropes are instances of properties: some take instantiated universals to be tropes, while others deny the existence of universals and take tropes to be ontologically fundamental. Historically, the bundling relation h...
متن کاملRealist Bundle Theory
1 that bears properties and individuates distinct particulars. However, most theorists agree that though it is possible that bearers are not individuators, considerations of simplicity favor identifying them. Tropes are often characterized as abstract particulars. This does not mean that tropes 2 are non-spatiotemporal, but, rather, that they cannot exist independently of the concrete particula...
