BookReview Symmetry and theMonster , One of the Greatest

A new book about simple groups has appeared, this one for general audiences. The title refers to the wide role of groups as symmetries in mathematics and science, as well as to the “monster”, a particular large finite simple group that has gotten much attention during the last three decades. The author, Mark Ronan, does research in groups and geometries. This book tells a history of simple grou...

Integrable variant of the one-dimensional Hubbard model

Abstract. A new integrable model which is a variant of the one-dimensional Hubbard model is proposed. The integrability of the model is verified by presenting the associated quantum R-matrix which satisfies the Yang-Baxter equation. We argue that the new model possesses the SO(4) algebra symmetry, which contains a representation of the η-pairing SU(2) algebra and a spin SU(2) algebra. Additiona...
