Kronecker delta. In mathematics, the Kronecker delta (named after Leopold Kronecker) is a function of two variables, usually just non-negative integers. The function is 1 if the variables are equal, and 0 otherwise: or with use of Iverson brackets : For example, because , whereas because . The Kronecker delta appears naturally in many areas of ...

A delta prism is an optical element providing a compact folded form of the Dove prism. [1] When used in the normal orientation, the prism inverts the image (that is, rotates it 180 degrees); rotating the orientation results in image rotation to other arbitrary angles. The base surface must be fabricated with a mirror coating to make it reflective.
Single delta potential. The time-independent Schrödinger equation for the wave function ψ(x) of a particle in one dimension in a potential V(x) is. where ħ is the reduced Planck constant, and E is the energy of the particle. The delta potential is the potential. where δ(x) is the Dirac delta function. It is called a delta potential well if ...
