= Schwartz–Bruhat function
{wiki=Schwartz–Bruhat_function}
The Schwartz–Bruhat function, often simply referred to as the Schwartz function, is a type of smooth function that is rapidly decreasing. Specifically, it belongs to the space of smooth functions that decay faster than any polynomial as one approaches infinity. This type of function is especially important in various areas of analysis, particularly in the fields of distribution theory, Fourier analysis, and partial differential equations.
