An Exceptional Collection For Khovanov Homology
The Temperley-Lieb algebra is a fundamental component of SU(2) topological
quantum field theories. We construct chain complexes corresponding to minimal
idempotents in the Temperley-Lieb algebra. Our results apply to the framework
which determines Khovanov homology. Consequences of our work include
semi-orthogonal decompositions of categorifications of Temperley-Lieb algebras
and Postnikov decompositions of all Khovanov tangle invariants

On February 26, 1997, the Fordham University School of Law hosted the Sixth Annual Stein Center Symposium on Contemporary Urban Challenges, entitled Urban Bioethics: A Symposium on Health Care, Poverty, and Autonomy. The Foreword introduces Articles in this Symposium issue and discusses two central themes of the various Articles: socioeconomic framing of bioethical and healthcare issues, and the challenge of the moral consensus
