Relational Bundle Geometric Formulation of Non‐Relativistic Quantum Mechanics

Fortschritte der Physik, EarlyView.
Abstract A bundle geometric formulation of non‐relativistic many‐particles Quantum Mechanics is presented. A wave function is seen to be a C$\mathbb {C}$‐valued cocyclic tensorial 0‐form on configuration space‐time seen as a principal bundle, while the Schrödinger equation flows from its covariant derivative, with the action functional supplying a ...

Existence and orthogonality of stable envelopes for bow varieties

Bulletin of the London Mathematical Society, EarlyView.
Abstract Stable envelopes, introduced by Maulik and Okounkov, provide a family of bases for the equivariant cohomology of symplectic resolutions. They are part of a fascinating interplay between geometry, combinatorics and integrable systems. In this expository article, we give a self‐contained introduction to cohomological stable envelopes of type A$A$

Homomorphisms similar to completely contractive homomorphims

Revista Técnica de la Facultad de Ingeniería, 2011
Paulsen has proved that a unital homomorphism from an operator algebra contained in a C* - algebra is similar to a completely contractive homomorphism if and only if it is completely bounded.

The relative dihedral homology of involutive algebras

International Journal of Mathematics and Mathematical Sciences, 1999
Let f:A→B be a homomorphism of involutive algebras A,B. The purpose of this paper is to define a free involutive algebra resolution of algebra B over f and use it to define and study the relative dihedral homology.

Homomorphisms of convolution algebras

Journal of Functional Analysis, 2011
AbstractWe establish an explicit, algebraic, one-to-one correspondence between the ⁎-homomorphisms, φ:L1(F)→M(G), of group and measure algebras over locally compact groups F and G, and group homomorphisms, ϕ:F→Mϕ, where Mϕ is a semi-topological subgroup of (M(G),w⁎).

Homomorphisms of Bunce-Deddens algebras [PDF]

Pacific Journal of Mathematics, 1992
The homomorphisms of a Bunce-Deddens algebra \(A\) are described. Necessary and sufficient conditions for an automorphism of the canonical UHF- subalgebra of \(A\) to have an extension to an automorphism of \(A\) are given.

Ring homomorphisms on real Banach algebras

International Journal of Mathematics and Mathematical Sciences, 2003
Let B be a strictly real commutative real Banach algebra with the carrier space ΦB. If A is a commutative real Banach algebra, then we give a representation of a ring homomorphism ρ:A→B, which needs not be linear nor continuous.

Representations of the cyclically symmetric q-deformed algebra $so_q(3)$

, 1998
An algebra homomorphism $\psi$ from the nonstandard q-deformed (cyclically symmetric) algebra $U_q(so_3)$ to the extension ${\hat U}_q(sl_2)$ of the Hopf algebra $U_q(sl_2)$ is constructed.

Finite models for positive combinatorial and exponential algebra

Bulletin of the London Mathematical Society, EarlyView.
Abstract We use high girth, high chromatic number hypergraphs to show that there are finite models of the equational theory of the semiring of non‐negative integers whose equational theory has no finite axiomatisation, and show this also holds if factorial, fixed base exponentiation and operations for binomial coefficients are adjoined.
