%0 Journal Article %T Ideals and structure of operator algebras %A Melahat Almus %A David P. Blecher %A Sonia Sharma %J Mathematics %D 2009 %I arXiv %X We continue the study of r-ideals, l-ideals, and HSA's in operator algebras. Some applications are made to the structure of operator algebras, including Wedderburn type theorems for a class of operator algebras. We also consider the one-sided $M$-ideal structure of certain tensor products of operator algebras. %U http://arxiv.org/abs/0907.3103v5
