In mathematics, the Kronecker delta (named after Leopold Kronecker) is a function of two variables, ... The last formula is equivalent to the Cauchy–Binet formula.
In mathematics, the classical Kronecker limit formula describes the constant term at s = 1 of a real analytic Eisenstein series (or Epstein zeta function) in terms of the Dedekind eta function. There are many generalizations of it to more complicated Eisenstein series.
In mathematics, Kronecker coefficients g λ μν describe the decomposition of the tensor product (= Kronecker product) of two irreducible representations of a symmetric group into irreducible representations. They play an important role algebraic combinatorics and geometric complexity theory.
In mathematics, the Iverson bracket, named after Kenneth E. Iverson, is a notation that generalises the Kronecker delta, which is the Iverson bracket of the statement x = y. It maps any statement to a function of the free variables in that statement. This function is defined to take the value 1 for the values of the variables for which the ...
In mathematics, the Kronecker product, sometimes denoted by ⊗, is an operation on two matrices of arbitrary size resulting in a block matrix.It is a specialization of the tensor product (which is denoted by the same symbol) from vectors to matrices and gives the matrix of the tensor product linear map with respect to a standard choice of basis.
In mathematics and classical ... is the Kronecker delta. ... Hamilton's equations for the time evolution of the system follow immediately from this formula. ...
The mathematical motivation for this type of notation, as well as additional Stirling number formulae, may be found on the page for Stirling numbers and exponential generating functions. Another infrequent notation is s 1 ( n , k ) {\displaystyle s_{1}(n,k)} and s 2 ( n , k ) {\displaystyle s_{2}(n,k)} .
The Kronecker delta is one of the family of generalized Kronecker deltas. The generalized Kronecker delta of degree 2 p may be defined in terms of the Kronecker delta by (a common definition includes an additional multiplier of p ! on the right):
