Summary

For more than a century, nonlinear analysis has had widespread and prominent applications in many areas of mathematics, including functional analysis, fixed point theory, control theory, nonlinear optimization, variational analysis, and nonlinear ordinary differential equations and partial differential equations, convex analysis, dynamical system theory, mathematical economics, signal processing, and so on. Various extensions of special functions and their associated polynomials include Bernoulli numbers and polynomials, Euler numbers and polynomials with other classical numbers such as the gamma function, the beta function, the multiple gamma function and some of its q extensions and other extensions Theory, Riemann zeta function, generalized (Hurwitz zeta) function, multiple Hurwitz zeta functions) have been widely promoted and applied in various fields such as applied mathematics, combinatorial mathematics, physics, astronomy and engineering. Mathematical inequalities have always been considered an important tool in mathematics and scientific research. Classical inequalities (such as Hlder's inequality, Minkowski's inequality, Jensen's inequality, Hermite-Hadamard inequality, Grss’s inequality, Chebyshev's inequality, etc.) have different applications in many branches of mathematics, such as functional analysis, optimization theory, numerical analysis, probability statistics, information theory, and so forth.
