SpletWeak Maximum Principle Brian Krummel January 26, 2016 We will consider the weak maximum principle, which states that a solution (in fact a subso-lution) to an elliptic di erential equation on an open set attains its maximum value on the boundary of . Let to be an open set in Rn. We de ne the boundary of to be @ = n; where denotes the closure of . In mathematics, the Hausdorff maximal principle is an alternate and earlier formulation of Zorn's lemma proved by Felix Hausdorff in 1914 (Moore 1982:168). It states that in any partially ordered set, every totally ordered subset is contained in a maximal totally ordered subset. The Hausdorff maximal principle is one of many statements equivalent to the axiom of choice over ZF (Zermelo–Fraenkel set theory without the axiom of choice). The principle is also called the Ha… taste soul düsseldorf

SpletTheorem 18.2 (Maximum principle: bis). If f(z) is de ned on a closed and bounded set Eand f is holomorphic on the interior, then jfjachieves its maximum on the boundary of E. Proof. Since Eis closed and bounded, it is compact. As fis continuous on E, it follows that jfjachieves it maximum somewhere on E. If f is constant there is nothing to prove.
