Private stochastic convex optimization: optimal rates in linear time [PDF]

open access: yesSymposium on the Theory of Computing, 2020
We study differentially private (DP) algorithms for stochastic convex optimization: the problem of minimizing the population loss given i.i.d. samples from a distribution over convex loss functions. A recent work of Bassily et al.

k-Fractional Estimates of Hermite–Hadamard Type Inequalities Involving k-Appell’s Hypergeometric Functions and Applications

open access: yesFractal and Fractional, 2019
The main objective of this paper is to obtain certain new k-fractional estimates of Hermite−Hadamard type inequalities via s-convex functions of Breckner type essentially involving k-Appell’s hypergeometric functions.

Infinitesimal Convexity Implies Local Convexity [PDF]

open access: yesIndiana University Mathematics Journal, 1974
(the tangent space at p) such that expU has no points of M onthe \inside" of L. By the inside of Lwe mean the component of a tubularneighbor hood with Ldeleted which corresponds to the negative multiplesof the orienting normal vector eld under exp. The exponential maps arethose of M.It is an immediate consequence of one of the standard interpretations ...

On $\mathscr{M}$-convex functions

open access: yesAIMS Mathematics, 2020
In this article, we introduce the notion of $\mathscr{M}$-convex functions, $\log$-$\mathscr{M}$-convex functions and the notion of quasi $\mathscr{M}$-convex functions. We derive some new analogues of Hermite-Hadamard like inequalities associated with $\

Characterization of tropical hemispaces by (P,R)-decompositions [PDF]

open access: yes, 2013
We consider tropical hemispaces, defined as tropically convex sets whose complements are also tropically convex, and tropical semispaces, defined as maximal tropically convex sets not containing a given point.

Impact of Concave and Convex Solid Surfaces By Liquid-Like Projectiles

open access: yesTikrit Journal of Engineering Sciences, 2007
A theoretical and experimental investigation of the normal impact of a flat-ended liquid slug onto ductile cylindrical solid targets is presented. The liquid slug is simulated by wax which is known to behave as a liquid in high speed impact situations ...

Parametric generalized (p,q)-integral inequalities and applications

open access: yesAIMS Mathematics, 2022
A new generalized (p,q)-integral identity is derived. Using this new identity as an auxiliary result, we derive new parametric generalizations of certain integral inequalities using the class of s-preinvex functions.
