Using techniques from algebraic topology we derive linear inequalities which relate the spectrum of a set of Hermitian matrices A I, . . . , A, E C" " " with the spectrum of the sum A + . . . + A,. These extend eigenvalue inequalities due to FREEDE-THOMPSON and HORN for sums of eigenvalues of two H

In this paper we extend the work of Fomin and Greene on noncommutative Schur functions by defining noncommutative analogs of Schubert polynomials. If the variables satisfy certain relations (essentially the same as those needed in the theory of noncommutative Schur functions), we prove a Pieri-type
