Nettet1. Introduction. In this work, we prove a hitherto unknown modular convexity property of the Lebesgue spaces with variable exponent, , which has far reaching applications in fixed point theory, remarkably even in the case in which the exponent is unbounded. Lebesgue spaces of variable-exponent ( ) were first mentioned in [ 1 ].

Uniform integrability is an extension to the notion of a family of functions being dominated in which is central in dominated convergence.Several textbooks on real analysis and measure theory use the following definition: Definition A: Let (,,) be a positive measure space.A set () is called uniformly integrable if ‖ ‖ <, and to … Nettet12. jul. 2024 · To summarize the preceding discussion of differentiability and continuity, we make several important observations. If f is differentiable at x = a, then f is continuous at x = a. Equivalently, if f fails to be continuous at x = a, then f will not be differentiable at x = a. A function can be continuous at a point, but not be differentiable there.
