Non-perturbative Quantization of Phantom and Ghost Theories: Relating Definite and Indefinite Representations
We investigate the non-perturbative quantization of phantom and ghost degrees of freedom by relating their representations in definite and indefinite inner product spaces. For a large class of potentials, we argue that the same physical information can be extracted from either representation. We provide a definition of the path integral for these theories, even in cases where the integrand may ...
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
15 صفحه اولDefinite and Indefinite Unitary Time Representations for Hilbert and Non-hilbert Spaces
Stable states (particles), ghosts and unstable states (particles) are discussed with respect to the time representations involved, their unitary groups and the induced Hilbert spaces. Unstable particles with their decay channels are treated as higher dimensional probability collectives with nonabelian probability groups U(n) generalizing the individual abelian U(1)-normalization for stable stat...
متن کاملAlgorithms for the Indefinite and Definite Summation
The celebrated Zeilberger algorithm which finds holonomic recurrence equations for definite sums of hypergeometric terms F (n, k) is extended to certain nonhypergeometric terms. An expression F (n, k) is called hypergeometric term if both F (n + 1, k)/F (n, k) and F (n, k+1)/F (n, k) are rational functions. Typical examples are ratios of products of exponentials, factorials, Γ function terms, b...
متن کاملPragmatic inference in definite and indefinite contexts
Previous studies have shown that children have difficulty inferring intended referents of definite/indefinite determiners: e.g., that ”Give me the ball” implies a specific ball, while ”Give me a ball” requests any ball from a larger set. Here, we show that these findings need not indicate a fragile capacity for pragmatic reasoning because adults only make such inferences within specific context...
