The top-order zonal polynomials $C_{k}(A)$ , and top-order invariant polynomials $C_{k_{1},\ldots ,k_{r}}(A_{1},\ldots ,A_{r})$ in which each of the partitions of $k ...

An unfashionable nineteenth century technique, invariant theory, has recently been used to study error-correcting codes. This technique is potentially of much wider application, is very powerful, ...

Shift-invariant spaces form a fundamental class of function spaces where elements can be represented as linear combinations of translates of one or more generating functions. This concept is pivotal ...
