| This module is an exercise on the continuity and differentiability of real functions. |
| The book then returns to foundations with chapters on contiguity and L2 differentiability. |
| Also, we consider the concept of general differentiability for fuzzy functions and we plot the h-curve to illustrate the region of convergence in different levels. |
| These functions are most widely used because of their easy differentiability but other variants are also possible. |
| Because of the demands of differentiability in distribution theory, the spaces of test-functions and their duals are somewhat more complicated. |
| For example, the important distinctions between continuity and differentiability and between uniform and pointwise continuity seem to have no basis in intuition. |
