Single-Level Differentiability for Interval-valued Functions

Ulcilea A. S. Leal, Gino Maqui, Geraldo N. Silva, Weldon Lodwick


This study uses the theory of single-level difference for interval-valued functions to propose the concept of single-level differentiability, illustrate its calculations, and investigate how its single-level derivative (SL-derivative) relates to other mathematical derivatives.
