Entire solutions for several complex partial differential-difference equations of Fermat type in ℂ2

open access: yesOpen Mathematics, 2021
By utilizing the Nevanlinna theory of meromorphic functions in several complex variables, we mainly investigate the existence and the forms of entire solutions for the partial differential-difference equation of Fermat type α∂f(z1,z2)∂z1+β∂f(z1,z2)∂z2m+f(

On the Growth Order and Growth Type of Entire Functions of Several Complex Matrices

open access: yesJournal of Function Spaces, 2020
In this paper, we establish an explicit relation between the growth of the maximum modulus and the Taylor coefficients of entire functions in several complex matrix variables (FSCMVs) in hyperspherical regions.

Quantum Groups, Coherent States, Squeezing and Lattice Quantum Mechanics [PDF]

open access: yes, 1993
By resorting to the Fock--Bargmann representation, we incorporate the quantum Weyl--Heisenberg ($q$-WH) algebra into the theory of entire analytic functions. The main tool is the realization of the $q$--WH algebra in terms of finite difference operators.

Mean-periodic functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1980
We show that any mean-periodic function f can be represented in terms of exponential-polynomial solutions of the same convolution equation f satisfies, i.e., u∗f=0(μ∈E′(ℝn)). This extends to n-variables the work of L.

From Euclidean to Minkowski space with the Cauchy-Riemann equations [PDF]

open access: yes, 2008
We present an elementary method to obtain Green's functions in non-perturbative quantum field theory in Minkowski space from calculated Green's functions in Euclidean space. Since in non-perturbative field theory the analytical structure of amplitudes is

Stochastic macromodeling of nonlinear systems via polynomial chaos expansion and transfer function trajectories [PDF]

open access: yes, 2014
A novel approach is presented to perform stochastic variability analysis of nonlinear systems. The versatility of the method makes it suitable for the analysis of complex nonlinear electronic systems. The proposed technique is a variation-aware extension
