Entire solutions of two certain Fermat-type ordinary differential equations

open access: yesOpen Mathematics, 2023
In this article, we investigate the precise expression forms of entire solutions for two certain Fermat-type ordinary differential equations: (a0f+a1f′)2+(a0f+a2f′)2=p{\left({a}_{0}f+{a}_{1}{f}^{^{\prime} })}^{2}+{\left({a}_{0}f+{a}_{2}{f}^{^{\prime} })}^

Sparse analytic systems

open access: yesForum of Mathematics, Sigma, 2023
Erdős [7] proved that the Continuum Hypothesis (CH) is equivalent to the existence of an uncountable family $\mathcal {F}$ of (real or complex) analytic functions, such that $\big \{ f(x) \ : \ f \in \mathcal {F} \big \}$ is countable for ...

Infinite growth of solutions of second order complex differential equation

open access: yesOpen Mathematics, 2018
In this paper we study the growth of solutions of second order differential equation f′′ + A(z)f′ + B(z)f = 0. Under certain hypotheses, the non-trivial solution of this equation is of infinite order.

Hyper Relative Order (p, q) of Entire Functions

open access: yesAnnals of the West University of Timisoara: Mathematics and Computer Science, 2017
After the works of Lahiri and Banerjee [6] on the idea of relative order (p, q) of entire functions, we introduce in this paper hyper relative order (p, q) of entire functions where p, q are positive integers with p>q and prove sum theorem, product ...

On the growth measures of entire and meromorphic functions focusing their generalized relative type and generalized relative weak type

open access: yesActa Universitatis Sapientiae: Mathematica, 2017
In this paper we study some comparative growth properties of composite entire and meromorphic functions on the basis of their generalized relative order, generalized relative type and generalized relative weak type with respect to another entire function.

Geometry of transcendental singularities of complex analytic functions and vector fields

open access: yesComplex Manifolds
On Riemann surfaces MM, there exists a canonical correspondence between a possibly multivalued function ΨX{\Psi }_{X} whose differential is single-valued (i.e. an additively automorphic singular complex analytic function) and a vector field XX.
