'''Singularity functions''' are a class of discontinues functions that contain [[Mathematical singularity|singularity]], i.e. they are discontinuous at its singular points. Singularity functions have been heavily studied in the field of mathematics under the alternative names of [[generalized functions]] and [[Distribution (mathematics)|distribution theory]]<ref>Distribution Theory and Transform Analysis, by A. H. Zemanian, New York: McGraw-Hill Book Company, 1965</ref><ref>Generalised Functions, Hoskins, Halsted Press, 1979</ref>. The functions are notated with brackets, as <math>\langle x-a\rangle ^n</math> where ''n'' is an integer. The "<math>\langle \rangle</math>" are often refereed as '''singularity brackets''' . The functions are defined as:
