An Investigation on the Basic Conceptual Foundations of Quantum Mechanics by Using the Clifford Algebra
We review our approach to quantum mechanics adding also some new interesting
results. We start by giving proof of two important theorems on the existence of
the and Clifford algebras. This last algebra gives proof of the von Neumann
basic postulates on the quantum measurement explaining thus in an algebraic
manner the wave function collapse postulated in standard quantum theory. In
this manner we reach the objective to expose a self-consistent version of
quantum mechanics. We give proof of the quantum like Heisenberg uncertainty
relations, the phenomenon of quantum Mach Zender interference as well as
quantum collapse in some cases of physical interest We also discuss the problem
of time evolution of quantum systems as well as the changes in space location.
We also give demonstration of the Kocken-Specher theorem, and also we give an
algebraic formulation and explanation of the EPR . By using the same approach
we also derive Bell inequalities. Our formulation is strongly based on the use
of idempotents that are contained in Clifford algebra. Their counterpart in
quantum mechanics is represented by the projection operators that are
interpreted as logical statements, following the basic von Neumann results.
Using the Clifford algebra we are able to invert such result. According to the
results previously obtained by Orlov in 1994, we are able to give proof that
quantum mechanics derives from logic. We show that indeterminism and quantum
interference have their origin in the logic.Comment: forthcoming papers; http://www.m-hikari.com/astp/forth/index.htm
Addendum to Quantum Wave Function Collapse of a System Having Three anti Commuting Elements.
We indicate a new way in the solution of the problem of the quantum measurement . In past
papers we used the well-known formalism of the density matrix using an algebraic approach in a two
states quantum spin system S, considering the particular case of three anticommuting elements. We
demonstrated that, during the wave collapse, we have a transition from the standard Clifford algebra,
structured in its space and metrics, to the new spatial structure of the Clifford dihedral algebra. This
structured geometric transition, which occurs during the interaction of the S system with the macroscopic
measurement system M, causes the destruction of the interferential factors. In the present paper we
construct a detailed model of the (S+M) interaction evidencing the particular role of the Time Ordering in
the (S+M) coupling since we have a time asymmetric interaction . We demonstrate that , during the
measurement , the physical circumstance that the fermion creation and annihilation operators of the S
system must be destroyed during such interaction has a fundamental role
The Painlev\'e methods
This short review is an introduction to a great variety of methods, the
collection of which is called the Painlev\'e analysis, intended at producing
all kinds of exact (as opposed to perturbative) results on nonlinear equations,
whether ordinary, partial, or discrete.Comment: LaTex 2e, subject index, Nonlinear integrable systems: classical and

Mobility and Equity for New York's Transit-Starved Neighborhoods: The Case for Full-Featured Bus Rapid Transit
New York City's public transportation system moves millions of people every day. But an increasing number who live in outer borough neighborhoods are stuck with unreliable transit options and long travel times tracked in hours, not minutes.It does not have to be this way.Developed by the Pratt Center for Community Development and funded by the Rockefeller Foundation, this report highlights the limitations of New York City's current public transit system, the adverse effects those limitations have on our economy and quality of life, and the role Bus Rapid Transit (BRT) can play in remedying these transit inequities.BRT has transformed cities across the world from Mexico City to Barcelona to Cleveland. At a fraction of the cost to build just a mile of subway rail, BRT gives riders a reliable way to get where they need to go.BRT is effective. It is innovative. And it could be the solution for New York's transit-starved neighborhoods
