We prove the following conjecture due to Bryant Mathews (2008). Let Qi be the orthogonal grassmannian of totally isotropic i-planes of a non-degenerate quadratic form q over an arbitrary field (where i is an integer satisfying 1 ≤ i ≤ m := [(dim q)/2]). Assume that for a given i, the form q has the following property (possessed by the generic quadratic form): the degree of each closed point on ...

We feel honoured to contribute this chapter to a volume that is devoted to recognizing the unique place that Andrew Mathews has had in the study of anxiety and the anxiety disorders. From the beginning of his career, he set the course for research on anxiety, including psychophysiology, treatment and, most recently, cognitive mechanisms. This chapter will relate predominantly to Mathews’ contri...

Treating problems in full general relativity is highly complex and frequently approximate methods are employed to simplify the solution. We present comparative solutions of a infinitesimally thin relativistic, stationary, rigidly rotating disk obtained using the full equations and the approximate approach suggested by Wilson & Mathews. We find that the Wilson-Mathews method has about the same a...

Fifty years ago, Max Mathews opened new territories for music as he implemented the first digital synthesis and the first digital recording of sound. This presentation illustrates some specific problems and possibilities of computer music, focusing on the perception of musical sound and reflecting the points of view of the author.
