Nettetdetermining integrability. Example 3. Since the discontinuity set of a continuous function is empty and the empty set has measure zero, the Riemann-Lebesgue theorem immediately implies that continuous functions on closed intervals are always integrable. Example 4.

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. NettetTools. In mathematics, integrability is a property of certain dynamical systems. While there are several distinct formal definitions, informally speaking, an integrable system is a dynamical system with sufficiently many conserved quantities, or first integrals, such that its behaviour has far fewer degrees of freedom than the dimensionality of ... compounding pharmacy refine

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.
