Singularity functions are a class of discontinuous functions that contain singularities, i.e. they are discontinuous at their singular points. Singularity functions have been heavily studied in the field of mathematics under the alternative names of generalized functions and distribution theory. The functions are notated with brackets, as where n is an integer. The "" are often referred to as singularity brackets . The functions are defined as:

  • Singularity functions are a class of discontinuous functions that contain singularities, i.e. they are discontinuous at their singular points. Singularity functions have been heavily studied in the field of mathematics under the alternative names of generalized functions and distribution theory. The functions are notated with brackets, as where n is an integer. The "" are often referred to as singularity brackets . The functions are defined as: where: δ(x) is the Dirac delta function, also called the unit impulse. The first derivative of δ(x) is also called the unit doublet. The function is the Heaviside step function: H(x) = 0 for x < 0 and H(x) = 1 for x > 0. The value of H(0) will depend upon the particular convention chosen for the Heaviside step function. Note that this will only be an issue for n = 0 since the functions contain a multiplicative factor of x − a for n > 0. is also called the Ramp function. (en)
  • Funções singulares são funções que pertencem a uma classe de funções descontínuas que contém singularidades, i.e. elas são descontínuas em seus pontos singulares. Tais funções são representadas como , onde n é o expoente do integrando, ou integrador. As funções são definidas como: Onde: δ(x) é a função Delta de Dirac, também chamada de impulso unitário. A função H(x-a) é a Função de Heaviside: H(x-a)=0 para x (pt)
