Unification of Bessel functions of different orders
We investigate the internal space of Bessel functions which is associated to
the group Z of positive and negative integers defining their orders. As a
result we propose and prove a new unifying formula (to be added to the huge
literature on Bessel functions) generating Bessel functions of real orders out
of integer order one's. The unifying formula is expected to be of great use in
applied mathematics. Some applications of the formula are given for
illustration.Comment: 8 pages,Late
Mapping Integer Order Neumann Functions To Real Orders
In a recent paper we unified Bessel functions of different orders .Here we
extend the unification to other linairely independant solutions to Bessel
equation, Neumann's and Hankel's functionsComment: 6 pages, Late
A deformation of Hermite polynomials
We propose and study the properties of a set of polynomials $M_{n\alpha, H\
}^{s}(z)C_{n\alpha, H}^{s}(z)W_{n\alpha, H}^{s}(z)n,s\in N;\alpha =\pm 1;HH_{n}(z).$The structure underlying the deformation seems quite general and not
only restricted to Hermite polynomials.Comment: 16 pages, Late
The associated Laguerre Polynomials
In a previous paper we deformed Hermite polynomials to three associated
polynomials .Here we apply the same deformation to Laguerre polynomials .Comment: Latex 2e, 12 page
Cohomological Quantum Mechanics And Calculability Of Observables
We reconsider quantum mechanical systems based on the classical action being
the period of a one form over a cycle and elucidate three main points. First we
show that the prepotenial V is no longer completely arbitrary but obeys a
consistency integral equation. That is the one form dV defines the same period
as the classical action. We then apply this to the case of the punctured plane
for which the prepotential is of the form .
The function is any but a periodic function of the polar angle. For
the topological information to be preserved, we further require that
be even. Second we point out the existence of a hidden scale which comes from
the regularization of the infrared behaviour of the solutions. This will then
be used to eliminate certain invariants preselected on dimensional counting
grounds. Then provided we discard nonperiodic solutions as being non physical
we compute the expectation values of the BRST- exact observables with the
general form of the prepotential using only the orthonormality of the solutions
(periodic). Third we give topological interpretations of the invariants in
terms of the topological invariants wich live naturally on the punctured plane
as the winding number and the fundamental group of homotopy,but this requires a
prior twisting of the homotopy structure.Comment: 12 pages,Late
The Trace Formula of the Spinoriel Amplitude
We re express the fermion's probability amplitude as a trace over spinor
indices, which formulation surprisingly does not exist in literature. This
formulation puts the probabilty amplitude and the the probabilty(squared
amplitude) of a given process on equal footing at the compuational level and
this is our principal motivation to write the present paper. We test the power
of the trace formula in three applications: Calculation of the charge-current
of fermions by using symbolic programs, which current so far was only
computable by hand, analytic compuation of the quark dipole magnetic moment,
rendered less cumbersome, and finally Fiertz rearrangement identities now made
more transparent.Comment: Work presented at: HEP 2009 16-22 July 2009, Krakow, Poland AND

Witten deformed exterior derivative and Bessel functions
In a recent paper we investigated the internal space of Bessel functions
associated with their orders. We found a formula (new) unifying Bessel
functions of integer and of real orders. In this paper we study the deformed
exterior derivative system on the puctured plane as a tentative
to understand the origin of the formula and find that indeed similar formula
occurs. This is no coincidence as we will demonstrate that generating functions
of integer order Bessel functions and of real orders are respectively
eigenstates of the usual exterior derivative and its deformation. As a direct
consequence we rediscover the unifying formula and learn that the system linear
in is related to Bessel theory much as the system quadratic in
() is related to Morse theory.Comment: 8 pages late
Magnetic moment versus tensor charge
We express the baryon magnetic moments in terms of the baryon tensor charges,
considering the quarks as relativistic interacting objects. Once tensor charges
get measured accurately, the formula for the baryon magnetic moment will serve
to extract precise information on the quark anomalous magnetic moment, the
quark effective mass and the ratio of the quark constituent mass to the quark
effective mass. The analogous formula for the baryon electric dipole moment is
of no great use as it gets eventually sizable contributions from various CP-
violating sources not necessary associated to the quark electric dipole moment.Comment: 15 pages pdf forma
Cohomology and Bessel functions Theory
By studying cohomological quantum mechanics on the punctured plane,we were
led to identify (reduced) Bessel functions with homotopic loops living on the
plane.This identification led us to correspondence rules between exponentials
and Bessel functions.The use of these rules makes us retrieve known but also
new formulas in Bessel functions theory.Comment: 11 pages .Latex2e.Talk given at Group24 Paris 15-20 July 200
Twisted Homotopy: A Group Theoretic Approach
After summarising the physical approach leading to twisted homotopy and after
developing the cohomological approach further with respect to our previous work
we propose a third alternative approach to twisted homotopy based on group
theoretic considerations. In this approach the fundamental group
isomorphic to Z which describes homotopic loops on the punctured plane is enhanced in a special way to the continuous SO(2) group . This is
performed by letting the parameter of the group while
keeping its generator unchanged .It is shown that such non-trivial procedure
has the effect of introducing well defined self-interactions among loops which
are at the basis of twisted homotopy where the angle plays the role
of the self coupling constant.
