In mathematical analysis, the smoothness of a function is a property measured by the number of continuous derivatives it has over some domain, called differentiability class. At the very minimum, a function could be considered smooth if it is differentiable everywhere (hence continuous). At the other end, it might also possess derivatives of all orders in its domain, in which case it is sai… WebAug 24, 2024 · Which of the commonly used "strong" topologies on the space of smooth compactly supported functions are equivalent to each other?

WebDec 1, 2014 · ==== It seems that there are infinitely many C ∞ functions that work, so long as the power series at x = π / 4 is consistent with the restrictions coming from taking derivatives of the above expression at π / 4. Each of these power series should correspond to an analytic function that satisfies the above equation in a neighborhood of x = π / 4.
