**Toward quantizing quantum mechanical systems using Hodge-de Rham theory**

*JP Journal of Geometry and Topology*F

2016-08-31

Empirical evidence of quantization is found in experiments demonstrating the Aharonov-Bohm and integer and fractional Quantum Hall effects. In the associated ongoing open areas of research there have been numerous attempts to explain the observed nature of such quantization. Of particular note, and one motivation for the topological concepts of space-time addressed here, is the occurrence of certain sequences of plateaus in fractional Quantum Hall results, represented by positive integer multiples of quantum units where nature selects certain integers as multipliers of fundamental quantum measures of electrical charge and magnetic flux. The micro-origins of such selections are unknown. Our recently deceased colleague, Evert Jan Post, espoused a universal view of integer and fractional QH impedance characterized by the ratio of period integrals for flux and charge, leading to a ratio of the corresponding quantum integers, often referred to as filling factors. Our main purpose in the present article is to build upon previous topological results toward the ultimate goal of accommodating singularities in a space-time Riemannian manifold,representing the experimentally observed specific sequences of integers and fractions as an extension of the familiar manoeuvres such as the residue theorem of Cauchy in complex analysis, or, in a more general topological setting of exterior calculus, Hodge-de Rham cohomology, and the Mittag-Leffler theorems. It is our ultimate intention to shed light on the nature of particles and space by examining such singular features through extensions of classical singularity theory to the space-time pseudo-Riemannian manifold.

**The Segal-Shale-Weil representation, the indices of Kashiwara and Maslov, and quantum mechannics**

*Expositiones Mathematicae*F

2015-12-31

We produce a connection between the Weil 2-cocycles defining the local and adelic metaplectic groups defined over a global field, i.e. the double covers of the attendant local and adelic symplectic groups, and local and adelic Maslov indices of the type considered by Souriau and Leray. With the latter tied to phase integrals occurring in quantum mechanics, we provide a formulation of quadratic reciprocity for the underlying field, first in terms of an adelic phase integral, and then in terms of generalized time evolution unitary operators.

**The Double Cover of the Real Symplectic Group and a Theme from Feynman’s Quantum Mechanics**

*International Mathematical Forum*F

2012-01-01

We present a direct connection between the 2-cocycle defining the double cover of the real symplectic group and a Feynman path integral describing the time evolution of a quantum mechanical system.

**Derived Categories and the Analytic Approach to General Reciprocity Laws: Part III**

*International Journal of Mathematics and Mathematical Sciences*F

2010-01-01

After developing topological and derived sheaf-categorical aspects of our quasidualization of Kubota’s formalism

**Derived Categories and the Analytic Approach to General Reciprocity Laws: Part II**

*International Journal of Mathematics and Mathematical Sciences*F

2007-01-01

Building on the topological foundations constructed in Part I, we now go on to address the homological algebra preparatory to the projected final arithmetical phase of our at- tack on the analytic proof of general reciprocity for a number field.

**Derived categories and the analytic approach to general reciprocity laws: Part I**

*International Journal of Mathematics and Mathematical Sciences*F

2005-01-01

We reformulate Hecke's open problem of 1923, regarding the Fourier-analytic proof of higher reciprocity laws, as a theorem about morphisms involving stratified topological spaces.

**A Sufficient Condition for Generating Heisenberg Groups over Local Fields**

*Far East Journal of Mathematical Science*F

2001-01-01

A Sufficient Condition for Generating Heisenberg Groups over Local Fields in the Far East Journal of Mathematical Science.

**Mach's Principle in a Mixed Newton-Einstein Context**

*Galilean Electrodynamics*F

1999-01-01

A closed physical space, in conjunction with scalar versus pseudo scalar distinctions, and an accordingly adapted Gauss theorem, reveal unexpected perspectives on Mach's principle, the mass-energy theorem, and a bonus insight into the nature of the solutions of the Einstein field equations of gravity.
