Unary operations | Special functions
In mathematics, the sign function or signum function (from signum, Latin for "sign") is an odd mathematical function that extracts the sign of a real number. In mathematical expressions the sign function is often represented as sgn. To avoid confusion with the sine function, this function is usually called the signum function. (Wikipedia).

Recall: what functions are invertible? Functions that pass the "horizontal line test" - that is, one-to-one functions. Is the sine function invertible? No. But if we restrict it to, say [-pi/2, pi/2], then it is invertible. So we define the inverse sine function to be the inverse of t

Abstract: A signed graph is a graph whose edges are labelled by a signature. It serves as a simple model of discrete vector bundle. We will discuss nodal domain theorems for arbitrary symmetric matrices by exploring the induced signed graph structure. This is an extension of the nodal doma

(October 21, 2013) Leonard Susskind introduces the spin statistics of Fermions and Bosons, and shows that a single complete rotation of a Fermion is not an identity operation, but rather induces a phase change that is detectable. Originally presented by the Stanford Continuing Studies Pro
