The Investigation of the Discrete Universality of L-Functions of Elliptic Curves

Jaunųjų Mokslininkų Darbai, 2022
In the paper, we prove the discrete universality theorem in the sense of the weak convergence of probability measures in the space of analytic functions for the L-functions of elliptic curves.

About the rate of rational approximation of some analytic functions

Mathematical Modelling and Analysis, 1998
The article is devoted to results relating to the theory of rational approximation of an analytic function. Let ƒ be an analytic function on the disk {z : |z| < ñ), ñ > 1. The rate of decrease of the best approximations ñn of a function ƒ by the rational

On tensor product approximation of analytic functions [PDF]

, 2015
We prove sharp, two-sided bounds on sums of the form ∑k∈ℕd0\𝒟a(T) exp(− ∑dj=1 ajkj), where 𝒟a(T) := {k ∈ ℕd0 : ∑dj=1 ajkj ≤ T} and a ∈ ℝd+.

Results on analytic functions defined by Laplace-Stieltjes transforms with perfect ϕ-type

Open Mathematics, 2020
In this paper, we introduce the concept of the perfect ϕ\phi -type to describe the growth of the maximal molecule of Laplace-Stieltjes transform by using the more general function than the usual.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

Extension of Dasgupta’s Technique for Higher Degree Approximation

Universitas Scientiarum, 2021
In the present paper, rational wedge functions for degree two approximation have been computed over a pentagonal discretization of the domain, by using an analytic approach which is an extension of Dasgupta’s approach for linear approximation.

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.
