Existence and Uniqueness of Non-Negative Solution to a Coupled Fractional q-Difference System with Mixed q-Derivative via Mixed Monotone Operator Method

Mathematics, 2023
In this paper, we study a nonlinear Riemann-Liouville fractional a q-difference system with multi-strip and multi-point mixed boundary conditions under the Caputo fractional q-derivative, where the nonlinear terms contain two coupled unknown functions ...

Prop-2-en-1-one Derivatives as Corrosion Inhibitors for Copper in 1 M HNO3

International Journal of Electrochemical Science, 2014
Inhibition of corrosion of copper in nitric acid by prop-2-en-1-one derivatives has been studied using weight loss and electrochemical measurements. It was found that the prop-2-en-1-one derivatives act as a good corrosion inhibitor for copper in all ...

Hamiltonian analysis of mixed derivative Hořava-Lifshitz gravity [PDF]

Physical Review D, 2016
This short note is devoted to the canonical analysis of the Horava-Lifshitz gravity with mixed derivative terms that was proposed in arXiv:1604.04215. We determine the algebra of constraints and we show that there is one additional scalar degree of freedom with respect to the non-projectable Horava-Lifshitz gravity.

A bivariate sampling series involving mixed partial derivatives

TURKISH JOURNAL OF MATHEMATICS, 2017
Summary: Recently Fang and Li established a sampling formula that involves only samples from the function and its first partial derivatives for functions from Bernstein space, \(B^{p}_{\sigma}(\mathbb{R}^{2})\). In this paper, we derive a general bivariate sampling series for the entire function of two variables that satisfy certain growth conditions ...

Time Fractional Derivatives and Evolution Equations

Bruno Pini Mathematical Analysis Seminar, 2017
In this seminar we introduce the fractional derivatives of Riemann-Liouville and Caputo, with some of their main properties. We conclude by illustrating certain results of maximal regularity for mixed initial-boundary value problems, evolving them.
