We prove a sufficient condition for the Jacobian problem in the setting of real, complex and mixed polynomial mappings. This follows from the study of the bifurcation locus of a mapping subject to a new Newton non-degeneracy condition.

We reexamine the quantization of a class of non-polynomial scalar field theories which interpolates continuously from a free one to φ 4 theory. The quantization of such theories is problematic because the Feynman rules may not be directly obtained. We give a means for calculating the correlation functions in this theory. The Feynman rules developed here shall enable further progress in the unde...

In this paper, we mainly investigate entire solutions of the following two non-linear differential-difference equations [see formula in PDF] and PDF], where is an integer, are non-zero constants, a non-vanishing polynomial non-constant polynomial. Under some additional hypotheses, analyze existence expressions transcendental above equations.

We show that the exact energy eigenvalues and eigenfunctions of the Schrödinger equation for charged particles moving in certain class of noncentral potentials can be easily calculated analytically in a simple and elegant manner by using Nikiforov and Uvarov (NU) method. We discuss the generalized Coulomb and harmonic oscillator systems. We study the Hartmann Coulomb and the ring-shaped and com...

Relaxing first-class constraint conditions in the usual Drinfeld-Sokolov Hamiltonian reduction leads, after symmetry fixing, to realizations of W algebras expressed in terms of all the J-current components. General results are given for G a non exceptional simple (finite and affine) algebra. Such calculations directly provide the commutant, in the (closure of) G enveloping algebra, of the nilpo...

This paper is an extension of a previous work where two nondeterminism analyses were presented. One of them was efficient but not very powerful and the other one was more powerful but very expensive. Here, we develop an intermediate analysis in both aspects, efficiency and power. The improvement in efficiency is obtained by speeding up the fixpoint calculation by means of a widening operator, a...

We extend a recent result on the existence of wandering domains of polynomial functions defined over the p-adic field Cp to any algebraically closed complete non-archimedean field CK with residue characteristic p > 0. We also prove that polynomials with wandering domains form a dense subset of a certain one-dimensional family of degree p + 1 polynomials in CK [z]. Given a rational function φ ∈ ...

We prove an inequality for polynomials applied in a symmetric way to non-commuting operators.
