On the sum of the Lah numbers and zeros of the Kummer confluent hypergeometric function

Acta Universitatis Sapientiae: Mathematica, 2018
In the paper, the authors find the sum of the Lah numbers and make sure that the Kummer confluent hypergeometric function 1F1(n+ 1; 2; z) has only n− 1real and negative zeros.

Study on new integral operators defined using confluent hypergeometric function

Advances in Difference Equations, 2021
Two new integral operators are defined in this paper using the classical Bernardi and Libera integral operators and the confluent (or Kummer) hypergeometric function.

Allosteric modulation of protein kinase A in individuals affected by NLPD‐PKA, a neurodegenerative disease in which the PRKAR1B L50R variant is expressed

The FEBS Journal, EarlyView.
In healthy neurons, Protein kinase A (PKA) forms a tetrameric holoenzyme enabling precise allosteric regulation. We characterized a novel neurodegenerative disease, neuronal loss, and parkinsonism driven by PRKAR1B mutation (NLPD‐PKA), demonstrating disrupted holoenzyme assembly, reduced cooperativity, and increased catalytic subunit nuclear ...

On the Matrix Versions of Incomplete Extended Gamma and Beta Functions and Their Applications for the Incomplete Bessel Matrix Functions

Complexity, 2021
In this paper, we first introduce the incomplete extended Gamma and Beta functions with matrix parameters; then, we establish some different properties for these new extensions. Furthermore, we give a specific application for the incomplete Bessel matrix

On Certain Solutions for Confluent and Double-Confluent Heun Equations [PDF]

arXiv, 2008
This paper examines some solutions for confluent and double-confluent Heun equations. In the first place, we review two Leaver's solutions in series of regular and irregular confluent hypergeometric functions for the confluent equation and introduce an additional expansion in series of irregular confluent hypergeometric functions.

Do temporary changes in earnings caused by mean reversion affect firms’ refinancing decisions?

Journal of Financial Research, EarlyView.
Abstract We develop a dynamic two‐stage trade‐off model with refinancing when earnings are mean reverting. Our model predicts a negative relation between profitability and leverage at refinancing due to conservative debt increases. With multiple rounds of refinancing, the leverage–profitability relation may turn positive when firms have substantial ...

Dynamic Keynesian Model of Economic Growth with Memory and Lag

Mathematics, 2019
A mathematical model of economic growth with fading memory and continuous distribution of delay time is suggested. This model can be considered as a generalization of the standard Keynesian macroeconomic model.

Holmgren problem for Helmholtz equation with the three singular coefficients [PDF]

E-Journal of Analysis and Applied Mathematics, 2019
Fundamental solutions for a multidimensional Helmholtz equation with three singular coefficients have been constructed recently which are expressed in terms of the confluent hypergeometric function in four variables.

Summation Formulas for the Confluent Hypergeometric Function , Φ_ 2^(2r) of Several Variables [PDF]

, 2019
In this paper, we establish a general summation formula for the confluent hypergeometric function Φ2(2r) of several variables by applying the generalized Kummer’s summation theorem due to Lavoie et al.
