Exponential Capillary Pressure Functions in Sedimentary Rocks [PDF]

open access: yesE3S Web of Conferences, 2019
The Brooks-Corey power-law capillary pressure model is commonly imposed on core analysis data without verifying the validity of its underlying assumptions.

Relation of Some Known Functions in terms of Generalized Meijer G-Functions

open access: yesJournal of Mathematics, 2021
The aim of this paper is to prove some identities in the form of generalized Meijer G-function. We prove the relation of some known functions such as exponential functions, sine and cosine functions, product of exponential and trigonometric functions ...

Approximation of analytic functions of exponential derived and integral bases in Fréchet spaces [PDF]

open access: yesAssiut University Journal of Multidisciplinary Scientific Research, 2022
The purpose of this paper is to establish some theorems on the representation of analytic functions by exponential derived bases (EDBs) and exponential integral bases (EIBs) in Fréchet spaces.

INCOMPLETE EXPONENTIAL SUMS OVER EXPONENTIAL FUNCTIONS [PDF]

open access: yesThe Quarterly Journal of Mathematics, 2014
We extend some methods of bounding exponential sums of the type $\displaystyle\sum_{n\le N}e^{2πiag^n/p}$ to deal with the case when $g$ is not necessarily a primitive root. We also show some recent results of Shkredov concerning additive properties of multiplicative subgroups imply new bounds for the sums under consideration.

Bounds for Quotients of Inverse Trigonometric and Inverse Hyperbolic Functions

open access: yesAxioms, 2022
We establish new simple bounds for the quotients of inverse trigonometric and inverse hyperbolic functions such as sin−1xsinh−1x and tanh−1xtan−1x. The main results provide polynomial bounds using even quadratic functions and exponential bounds under the

Some remarks on Cîrtoaje’s conjecture

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we give new conditions under which the Cîrtoaje’s conjecture is also valid. We also show that a certain generalization of the Cîrtoaje’s inequality fulfils an interesting property.
