%0 Journal Article %T Some cases on Strassen additive conjecture %A Youngho Woo %J Mathematics %D 2014 %I arXiv %X In this article, we verify the additivity for rank of a sum of coprime monomials and bivariate polynomials generalizing the result in (\cite{CCG}). We also show similar results hold for cactus rank. %U http://arxiv.org/abs/1406.2213v2
