Research in neuroscience has seen a recent trend toward the extension of receptive field (RF) estimation techniques and theoretical principles from linear to non-linear models. This development has ...

Let Q be an n x n symmetric matrix with integral entries and with det Q ≠ O, but not necesarily positive definite. We describe a generalized LLL algorithm to reduce this quadratic form. This algorithm ...

Invariant polynomials with matrix arguments have been defined by the theory of group representations, generalizing the zonal polynomials. They have developed as a useful tool to evaluate certain ...
