%0 Journal Article %T Strange Nonchaotic Attractors in Harper Maps %A Alex Haro %A Joaquim Puig %J Physics %D 2005 %I arXiv %R 10.1063/1.2259821 %X We study the existence of Strange Nonchaotic Attractors (SNA) in the family of Harper maps, proving that they are typical but not robust in this family. Our approach is based on the theory of linear skewproducts and the spectral theory of Schrodinger operators. %U http://arxiv.org/abs/nlin/0510073v1
