We connect the algebraic geometry and representation theory associated to Freudenthal's magic square. We give unified geometric descriptions of several classes of orbit closures, describing their hyperplane sections and desingularizations, and interpreting them in terms of composition algebras. In p

In the square-gradient theory, the Helmholtz free energy density of a nonuniform fluid is approximated by that of a uniform fluid plus a term proportional to the square of the density gradient. Presented here is the extension of this theory (and the corresponding theory of the chemical potential) to
Determining the clique number of the Paley graph of order q, 4 E I (mod 4) a prime power, is a difficult problem. However, the work of Blokhuis implies that in the Paley graph of order q2, where q is any odd prime power, the clique number is in fact q. In this paper we construct maximal cliques of s
