Even in the case where the metric space is a finite dimensional normed space, this is a subtle problem, as the map need not be a Lipschitz contraction or the space need not be bounded, so neither the contraction mapping theorem nor the Brouwer fixed point theorem applies. Election systems are critical infrastructure, protecting elections is part of national security. The right to vote, and to know that the winners are legitimate, is fundamental to American democracy. This talk will present the election data ecosystem and practical challenges to consolidating data. We will discuss recent innovations in using anomaly detection to protect the integrity of elections, drawing examples from the 2020 US Elections. Convergence theory for numerical schemes to approximate solutions of stochastic parabolic equations of the form$$du + A(u) \, dt = f \, dt + g \, dW, \qquad u(0)=u^0,$$ Tevian Dray article featured in AMM December issue The December 2020 Issue of theAmerican Mathematical Monthly (published by the Mathematical Association of America, and now available online at maa.org) features an article by Tevian Dray:"Using Embedding Diagrams to Visualize Curvature".Abstract: We give an elementary treatment of the curvature of surfaces of revolution in the language of vector calculus, using differentials rather than an explicit parameterization. We illustrate some basic features of curvature using embedding diagrams, and then use such a diagram to analyze the geometry of the Schwarzschild black hole.
