Fixed Point Methods for the Generalized Stability of Functional Equations in a Single Variable

open access: yesFixed Point Theory and Applications, 2008
We discuss on the generalized Ulam-Hyers stability for functional equations in a single variable, including the nonlinear functional equations, the linear functional equations, and a generalization of functional equation for the square root spiral.

Robust Classification of Functional and Quantitative Image Data Using Functional Mixed Models [PDF]

open access: yes, 2012
This paper describes how to perform classification of complex, high-dimensional functional data using the functional mixed model (FMM) framework. The FMM relates a functional response to a set of predictors through functional fixed and random effects ...
