String Homology of a Product of Spheres and the Witt Algebra
(Nova Science Publishers, Inc.; www.novapublishers.com; reprinted with permission from Nova Science Publishers, Inc., 2007)
Let X be a finite product of even dimensional spheres, we show that the string homology of X contains a finite product of copies of the Witt Lie algebra.
Homotopy Lie Algebra of Spaces for Hyperbolic Coformal 2-Cones
(International Press; http://www.intlpress.com/HHA/, 2004)
In this paper, we show that the rational homotopy Lie algebra of classifying spaces for certain types of hyperbolic coformal 2-cones is not nilpotent.
