We review the recently proposed unreduced, complex-dynamical solution to many-body problem with arbitrary interaction and its application to unified solution of fundamental problems, including foundat...
Iterative Solution of Maxwell's Equations for an Induction Motor
Iterative Solution of Maxwell's Equations Induction Motor General Physics
2012/4/19
In this work we use classical electromagnetism to analyse a three-phase induction motor. We first cast the motor as a boundary value problem involving two phenomenological time-constants. These are de...

Abstract: Integral balance solution employing entire domain approximation and the penetration dept concept to the Stokes' first problem of a viscoelastic generalized second grade fluid has been develo...
A solution of the non-uniqueness problem of the Dirac Hamiltonian and energy operators
non-uniqueness problem Dirac Hamiltonian energy operators General Relativity and Quantum Cosmology
2011/10/9
Abstract: In a general spacetime, the possible choices for the field of orthonormal tetrads lead (in standard conditions) to equivalent Dirac equations. However, the Hamiltonian operator is got from r...

Abstract: We solve problem 11585 proposed by B. Burdick, AMM June-July 2011 {bf 118} (6), p. 558 for the sum of certain products of Riemann zeta function values. We further point out an alternating su...
A solution of the Gross-Witten matrix model by nonlinear random processes
imulation methods planar approximation lattice field theory random processes
2011/1/14
We illustrate the stochastic method for solving the Schwinger-Dyson equations in large-N quantum field theories described in ArXiv:1009.4033 on the example of the Gross-Witten unitary matrix model.
A geometric solution to the coincidence problem, and the size of the landscape as the origin of hierarchy
geometric solution coincidence problem landscape
2010/12/21
Without assuming necessary conditions for observers such as galaxies or entropy production, we
show that the causal patch measure predicts the coincidence of vacuum energy and present matter
density...
Towards a non-anthropic solution to the cosmological constant problem
non-anthropic solution cosmological constant problem
2010/12/21
Many probability measures in the multiverse depend exponentially on some observable parameters,
giving rise to potential problems such as youngness bias, Q-catastrophe etc. In this paper we explore a...
Difference L operators and a Casorati determinant solution to the T-system for twisted quantum affine algebras
T-system quantum affine algebras
