short but complete version of Laplace's argument for an elementary proof of the following Stirling's formula [J. Stirling, Methodus Differentialis (London, 1730)]: Γ(α)≈[(α-1)/e] α-1 [2π(α-1)] 1/2 as α→∞, in the sense that the ratio of the two sides tends to 1....
An elementary proof of the continuity from $L_0^2(\\Omega)$ to $H^1_0(\\Omega)^n$ of Bogovskii's right inverse of the divergence The existence of right inverses of the divergence as an operator form $H^1_0(\\Omega)^n$ to $L_0^2(\\Omega)$ is a problem that has been ...
Here, van der Hofstad and Keane demonstrate an elementary proof of the random walk hitting time theorem. By introducing some notation, they derive a slightly stronger result than in theorem 1. 关键词: RANDOM walks (Mathematics) MATHEMATICAL analysis NUMERICAL analysis STOCHASTIC processes MATHEMATICAL ...

We present a new converse mean value theorem, with a rather elementary proof. The goal of this note is to present a simple proof for a converse mean-value theorem. Given a differentiable function f: [a, b] → R and a point c∈]a, b[, are there reals a...
