Extended precision

Extended precision refers to floating-point number formats that provide greater precision than the basic floating-point formats. Extended precision formats support a basic format by minimizing roundoff and overflow errors in intermediate values of expressions on the base format. In contrast to extended precision, arbitrary-precision arithmetic refers to implementations of much larger numeric types (with a storage count that usually is not a power of two) using special software (or, rarely, hardware).

Replacement Theorem

Welcome to the replacement theorem, which is *the* theorem that makes linear algebra work. Intuitively it says that any linearly independent set can be extended to be a spanning set. In this video, I state the replacement theorem and show some cool consequences. For example, using this the

R. Bamler - Uniqueness of Weak Solutions to the Ricci Flow and Topological Applications 3

I will present recent work with Kleiner in which we verify two topological conjectures using Ricci flow. First, we classify the homotopy type of every 3-dimensional spherical space form. This proves the Generalized Smale Conjecture and gives an alternative proof of the Smale Conjecture, wh

The matching polytope has exponential extension complexity - Thomas Rothvoss

Thomas Rothvoss University of Washington, Seattle March 17, 2014 A popular method in combinatorial optimization is to express polytopes P P , which may potentially have exponentially many facets, as solutions of linear programs that use few extra variables to reduce the number of constrain
