Title: | The invariant polynomials degrees of the Kronecker sum of two linear operators and additive theory | Authors: | Caldeira, Cristina Silva, J. A. Dias da |
Keywords: | Additive number theory; Derivations; Invariant polynomials | Issue Date: | 2000 | Citation: | Linear Algebra and its Applications. 315:1-3 (2000) 125-138 | Abstract: | Let G be an abelian group. Let A and B be finite non-empty subsets of G. By A+B we denote the set of all elements a+b with a[set membership, variant]A and b[set membership, variant]B. For c[set membership, variant]A+B, [nu]c(A,B) is the cardinality of the set of pairs (a,b) such that a+b=c. We call [nu]c(A,B) the multiplicity of c (in A+B). | URI: | https://hdl.handle.net/10316/4654 | DOI: | 10.1016/S0024-3795(00)00125-7 | Rights: | openAccess |
