Higher Order Derivatives in Costa’s Entropy Power Inequality [PDF]

IEEE Transactions on Information Theory, 2014
Let X be an arbitrary continuous random variable and Z be an independent Gaussian random variable with zero mean and unit variance. For t > 0, Costa proved that e2h(X+√t Z) is concave in t, where the proof hinged on the first and second order derivatives

Computation of higher order Lie derivatives on the Infinity Computer

Journal of Computational and Applied Mathematics, 2021
In this paper, we deal with the computation of Lie derivatives, which are required, for example, in some numerical methods for the solution of differential equations. One common way for computing them is to use symbolic computation.

Existence of Positive Solutions for a Higher-Order Fractional Differential Equation with Multi-Term Lower-Order Derivatives

Mathematics, 2021
This paper deals with the study of the existence of positive solutions for a class of nonlinear higher-order fractional differential equations in which the nonlinear term contains multi-term lower-order derivatives.

Bounds and algorithms for the K-Bessel function of imaginary order [PDF]

, 2013
Using the paths of steepest descent, we prove precise bounds with numerical implied constants for the modified Bessel function of imaginary order and its first two derivatives with respect to the order.

Analytic First-Order Derivatives of CASPT2 with IPEA shift

, 2023
Complete active space second-order perturbation theory (CASPT2) is useful for accurately predicting properties of complex electronic structures, but it is well known that it systematically underestimates excitation energies.

Solving Higher-Order Fractional Differential Equations by the Fuzzy Generalized Conformable Derivatives

Applied Computational Intelligence and Soft Computing, 2021
In this paper, the generalized concept of conformable fractional derivatives of order q∈n,n+1 for fuzzy functions is introduced. We presented the definition and proved properties and theorems of these derivatives.

Higher derivative extension of 6D chiral gauged supergravity [PDF]

, 2012
Six-dimensional (1, 0) supersymmetric gauged Einstein-Maxwell supergravity is extended by the inclusion of a supersymmetric Riemann tensor squared invariant. Both the original model as well as the Riemann tensor squared invariant are formulated off-shell

A Study of Some Families of Multivalent q-Starlike Functions Involving Higher-Order q-Derivatives

Mathematics, 2020
In the present investigation, by using certain higher-order q-derivatives, the authors introduce and investigate several new subclasses of the family of multivalent q-starlike functions in the open unit disk.
