1. In mathematics and functional analysis, a property of a function or distribution where it is zero outside a compact set (a closed and bounded set in Euclidean space)
A function has compact support if its closure is a compact set and it vanishes outside this set.
Uma função tem suporte compacto se seu fecho é um conjunto compacto e ela se anula fora deste conjunto.
2. Used in partial differential equations and analysis to describe functions that are nonzero only on a bounded region
Test functions with compact support are essential in distribution theory.
Funções teste com suporte compacto são essenciais na teoria de distribuições.
