WebFrankel conjecture, proved by Mori [Mor] and Siu-Yau [SY], states that if X admits a K¨ahler metric of positive bisectional curvature then it is biholomorphic to Pn. There has been much interest in obtaining a proof of this using the K¨ahler-Ricci flow: ∂ ∂t g¯kj = g − R¯kj. (1.1) In set theory, Zermelo–Fraenkel set theory, named after mathematicians Ernst Zermelo and Abraham Fraenkel, is an axiomatic system that was proposed in the early twentieth century in order to formulate a theory of sets free of paradoxes such as Russell's paradox. Today, Zermelo–Fraenkel set theory, with the historically controversial axiom of choice (AC) included, is the standard form of axiomatic set theory and as such is the most common foundation of mathem…

WebIn algebra and number theory, Wilson's theorem states that a natural number n > 1 is a prime number if and only if the product of all the positive integers less than n is one less than a multiple of n.That is (using the notations of modular arithmetic), the factorial ()! = satisfies ()! exactly when n is a prime number. In other words, any number n is a prime number if, … WebIn differential geometry, Fenchel's theorem is an inequality on the total absolute curvature of a closed smooth space curve, stating that it is always at least .Equivalently, the average … swanstrom ear wire forming pliers
