Fixed Points of Meromorphic Functions and Their Higher Order Differences and Shifts
In this paper, we investigate the relationships between fixed points of meromorphic functions, and their higher order differences and shifts, and generalize the case of fixed points into the more general case for first order difference and shift ...

The Beckman-Quarles theorem for continuous mappings from C^n to C^n
Let varphi_n:C^n times C^n->C, varphi_n((x_1,...,x_n),(y_1,...,y_n))=sum_{i=1}^n (x_i-y_i)^2. We say that f:C^n->C^n preserves distance d>=0, if for each X,Y in C^n varphi_n(X,Y)=d^2 implies varphi_n(f(X),f(Y))=d^2. We prove: if n>=2 and a continuous f:C^

Transcendental holomorphic maps between real algebraic manifolds in a complex space
We give an example of a real algebraic manifold embedded in a complex space that does not satisfy the Nash-Artin approximation Property. This Nash-Artin approximation Property is closely related to the problem of determining when the biholomorphic ...

New Characterization of Appell polynomials
We prove characterizations of Appell polynomials by means of symmetric property. For these polynomials, we establish a simple linear expression in terms of Bernoulli and Euler polynomials. As applications, we give interesting examples.

The correlation between the convergence of subdivision processes and solvability of refinement equations. [PDF]
We consider a univariate two-scale difference equation, which is studied in approximation theory, curve design and wavelets theory. This paper analysis the correlation between the existence of smooth compactly supported solutions of this equation and the

We show that stochastically continuous, time-homogeneous affine processes on the canonical state space $\Rplus^m \times \RR^n$ are always regular. In the paper of \citet{Duffie2003} regularity was used as a crucial basic assumption.

In this paper, we investigate the value distribution of meromorphic solutions of homogeneous and non-homogeneous complex linear differential-difference equations, and obtain the results on the relations between the order of the solutions and the ...

Fixed points of the smoothing transform: Two-sided solutions
Given a sequence $(C,T) = (C,T_1,T_2,...)$ of real-valued random variables with $T_j \geq 0$ for all $j \geq 1$ and almost surely finite $N = \sup\{j \geq 1: T_j > 0\}$, the smoothing transform associated with $(C,T)$, defined on the set $\mathcal{P}(\R)$

Geometric properties of basic hypergeometric functions
In this paper we consider basic hypergeometric functions introduced by Heine. We study mapping properties of certain ratios of basic hypergeometric functions having shifted parameters and show that they map the domains of analyticity onto domains convex ...

Cosine and sine addition and subtraction law with an automorphism [PDF]
Let S be a semigroup. Our main result is that we describe the complex-valued solutions of the following functional equationsg(xσ(y)) = g(x)g(y) + f(x)f(y), x, y ∈ S,f(xσ(y)) = f(x)g(y) + f(y)g(x), x, y ∈ S,andf(xσ(y)) = f(x)g(y) - f(y)g(x), x, y ∈ S ...
