A radial variable for de Sitter two-point functions
SciPost Physics, 2023 We introduce a "radial" two-point invariant for quantum field theory in de Sitter (dS) analogous to the radial coordinate used in conformal field theory.

Finiteness of meromorphic functions on an annulus sharing four values regardless of multiplicity [PDF]
Mathematica Bohemica, 2020 This paper deals with the finiteness problem of meromorphic funtions on an annulus sharing four values regardless of multiplicity. We prove that if three admissible meromorphic functions $f_1$, $f_2$, $f_3$ on an annulus $\mathbb A({R_0})$ share four ...

On a Non-Newtonian Calculus of Variations [PDF]
Axioms, 2021 The calculus of variations is a field of mathematical analysis born in 1687 with Newton’s problem of minimal resistance, which is concerned with the maxima or minima of integral functionals.

Journal of Geometric Analysis, 2023 We prove a Fatou-type theorem and its converse for certain positive eigenfunctions of the Laplace–Beltrami operator L on a Harmonic NA group. We show that a positive eigenfunction u of L with eigenvalue β2- ρ2 , where β∈ (0 , ∞) , has admissible limit in

On admissible entire solutions of Pell type functional equation f2 + ag2 = 1
, 2019 Given a non-zero entire function a, we would like to find entire functions f and g such that a is a small function of f and g and the pair (f,g) satisfies the Pell type functional equation: f2+ag2=1.

Admissible nested covariance models over spheres cross time [PDF]
Stochastic environmental research and risk assessment (Print), 2018 Nested covariance models, defined as linear combinations of basic covariance functions, are very popular in many branches of applied statistics, and in particular in geostatistics.

Equivalence of the chern-simons state and the Hartle-Hawking and Vilenkin wave functions [PDF]
, 2020 We show that the Chern-Simons (CS) state when reduced to minisuperspace is the Fourier dual of the Hartle-Hawking (HH) and Vilenkin (V) wave functions of the Universe.

Differential subordinations for functions with positive real part using admissibility conditions [PDF]
Asian-European Journal of Mathematics, 2021 Some sufficient conditions on certain constants which are involved in some first and second-order differential subordinations associated with certain functions with positive real part like modified Sigmoid function, exponential function and Janowski function are obtained so that the analytic function [Formula: see text] normalized by the condition ...
