 Dec1 comment Young's inequality for convolutions If you have it available, I tend to think the most natural way to approach this would be with $H\ddot{o}lder's$inequality. Nov25 answered Basic set theory proof Nov25 answered without using l'hopital rule Nov18 answered Question about modular arithmetic notation Nov15 awarded Yearling Nov14 answered Would taking a course in Linear Algebra help with working with Matlab? Nov14 comment In the Riemann sphere 1 is not summe of holomorphics map vanishing on 0 and $\infty$ Would you be all right with using Liouville's Theorem in the proof?

Jul19 answered Are axioms assumed to be true in a formal system? Jul7 answered order of dihedral Apr7 comment How many non-ordered quadruples satisfy $a+b+c+d=18$?

Aug5 comment Adjustable Sigmoid Curve (S-Curve) from (0,0) to (1,1) I'm not sure if it has the analytic properties that you want, but the CDF of a beta distribution is pretty versatile and meets your explicit requirements.
