The Kronecker delta has the so-called sifting property that for : = =. and if the integers are viewed as a measure space, endowed with the counting measure, then this property coincides with the defining property of the Dirac delta function () = (), and in fact Dirac's delta was named after the Kronecker delta because of this analogous property ...
The delta function was introduced by physicist Paul Dirac, and has since been applied routinely in physics and engineering to model point masses and instantaneous impulses. It is called the delta function because it is a continuous analogue of the Kronecker delta function, which is usually defined on a discrete domain and takes values 0 and 1.
This 'surface delta function' has the following property: [4] ... Kronecker delta, a function that can be viewed as an indicator for the identity relation;
Delta function may also refer to: Kronecker delta , a function of two variables which is one for equal arguments and zero otherwise, and which forms the identity element of an incidence algebra Modular discriminant (Δ), a complex function in Weierstrass's elliptic functions

The Kronecker delta is one of the family of generalized Kronecker deltas. The generalized Kronecker delta of degree 2p may be defined in terms of the Kronecker delta by (a common definition includes an additional multiplier of p! on the right):
