Meromorphic function sharing three sets with its shift, q-shift, q-difference and analogous operators
Journal Title: Математичні Студії - Year 2019, Vol 52, Issue 1
Abstract
Using the notion of weighted sharing of three sets we deal with the uniqueness problem of meromorphic function with its shift, q-shift, q-difference and analogous operator. A handful number of examples have been provided to substantiate our certain claims. In other words, we deduce conditions providing a) f(z)≡tf(z+c), where tn=1, n≥2; b) f(z)≡tf(qz+c), where tn=1, n≥2 and q,c∈C∖{0}; c) f(z)≡tf(qz), where tn=1 and ∣q∣=1; d) f(z)≡χnΔqf for n≥2 with Δqf=f(qz)−f(z) and χn={1,t,if n=2,if n≥3,tn=1.

Compositions of Dirichlet series similar to the Hadamard compositions, and convergence classes
Let (λn) be a positive sequence increasing to +∞, m≥2 and Dirichlet series Fj(s)=∑∞n=0an,jexp{sλn} (j=1,2,…,m) have the abscissa A∈(−∞,+∞] of absolute convergence. We say that Dirichlet series F(s)=∑∞n=0anexp{sλn} like t...

On the transcendental meromorphic solutions of a certain class of differential equations
In this paper we consider the differential equation F(k)−a2=eγ{α(F−a1)+β}, where ai(z),α(z)(≢0,∞), β(z)(≢∞), i=1,2 are small functions of F, γ is an entire function and k∈N. Let f be a transcendental meromorphic functi...

Analogues of Hausdorff dimension, upper and lower box dimensions for the inclusion hyperspaces and non-additive regular measures (capacities) on metric compacta are introduced. Their relations to the respective dimension...
Analysis the solutions of the differential nonlinear equations describing the information spreading process with jump discontinuity
In this paper, we introduce a mathematical model of spreading any type of information. The model has the form of a system of nonlinear differential equations with non-stationary parameters. We have suggested the explicit...
