Spatial $\alpha$-Zindler curves - Mathematics Stack Exchange The definition of an $\\alpha$-Zindler curve can be readily extended to 3 dimensions with chord length c and the perimeter cut into 2 parts of length ratio $\\alpha$ Can an $\\alpha$-Zindler curve be
Bounding a masked and weighted Dirichlet series Motivation: I am working with a residual series that in which each term is multiplied by a patterned binary mask I am able to bound the series without the mask but am struggling to bound the serie
Why can we interchange summations? - Mathematics Stack Exchange This isn't a proof, but perhaps can give you the insight you are looking for Any nondecreasing sequence converges to its (possibly infinite) supremum Thus a series of nonnegative terms converges to the supremum of its partial sums and interchanging the order of summation doesn't affect the value of the supremum: there is no accidental cancellation of terms of opposite sign
