Compact support maths
WebNext we de ne the support of a distribution and introduce the localization of a distribu-tion to an open set. We invoke partitions of unity to show that a distribution is uniquely determined by its localizations. Finally we discuss distributions with compact support and identify them with continuous linear forms on C∞. Moreover, we completely ...

WebIn mathematics, a bump function (also called a test function) is a function on a Euclidean space which is both smooth (in the sense of having continuous derivatives of all orders) and compactly supported. WebFor every compact Kˆ there exist an integer N 0 and a constant Csuch that j( ˚)j Ck˚k CN for every ˚2C1with support contained inside K: (1.6) In other words, for all test functions ˚which vanish outside a given compact set K, the value ( ˚) should be bounded in terms of the maximum value of derivatives of ˚, up to a certain order N. 4
