RT Journal Article T1 Homogeneous orthogonally additive polynomials on Banach lattices A1 Llavona, José G. A1 Benyamini, Yoav A1 Lassalle, Silvia AB The main result in this paper is a representation theorem for homogeneous orthogonally additive polynomials on Banach lattices. The representation theorem is used to study the linear span of the set of zeros of homogeneous real-valued orthogonally additive polynomials. It is shown that in certain lattices every element can be represented as the sum of two or three zeros or, at least, can be approximated by such sums. It is also indicated how these results can be used to study weak topologies induced by orthogonally additive polynomials on Banach lattices.
