A Kronecker delta is a compact notation that indicates the equivalent of a dot product in vector notations. In this usage, it takes the form of a Greek letter delta with two subscripts which indicate that the components are to be multiplied if the...

In mathematics, the Kronecker delta or Kronecker's delta, named after Leopold Kronecker (1823-1891), is a function of two variables, usually integers, which is 1 if they are equal, and 0 otherwise. So, for example, \delta_{12} =...

This article presents Kronecker product algorithms for constructing sums of squares and covariance matrices in complete, balanced designs. The algorithms can be applied to fixed, random, or mixed models with any number of factors. The covariance matrices are constructed under the usual infinite and...

The convent hadn't absorbed her completely. Silky strands of dark hair escaped from underneath her black habit. The eyes, now burdened with heavy bags and shadows, nevertheless appeared bright and sharp. A deceptively diminutive gold cross lay between her heavily cloaked breasts. A clumsy,...
