Numerical methods for solving first and second order fuzzy differential equations [PDF]

, 2014
Fuzzy differential equations (FDEs) with fuzzy initial conditions are studied as a suitable setting for the modeling of problems in science and engineering in which uncertainties or vagueness prevails.

Statistical expansions and locally uniform Fréchet differentiability [PDF]

, 1991
Estimators which have locally uniform expansions are shown in this paper to be asymptotically equivalent to M-estimators. The M-functionals corresponding to these M-estimators are seen to be locally uniformly Fréchet differentiable.

Differentiability of Lyapunov exponents

, 2020
We prove differentiability of certain linear combinations of the Lyapunov spectra of a flow on a principal bundle of a semi-simple Lie group. The specific linear combinations that yield differentiability are determined by the finest Morse decomposition ...

An Extension of the Carathéodory Differentiability to Set-Valued Maps

This paper uses the generalization of the Hukuhara difference for compact convex set to extend the classical notions of Carathéodory differentiability to multifunctions (set-valued maps). Using the Hukuhara difference and affine multifunctions as a local

Fréchet and Gateaux gH-Differentiability for Interval Valued Functions of Multiple Variables

In this work we extend concepts of differentiability for Interval-Valued functions (IV-functions) of multiple variables, based on generalized Hukuhara gH-difference.
