W. Edwards Deming on Teaching and Research

According to Deming, there is a close link between teaching and research. We present some of his contributions to to statistical theory and methods, as well as his perspective on teaching and research.

A. W. F. Edwards and the Origin of Bayesian Phylogenetics

In the early 1960s, Anthony Edwards and Luca Cavalli-Sforza made an effort to apply R. A. Fisher’s maximum-likelihood method to estimate genealogical trees of human populations using gene-frequency data. They used the Yule branching process to describe the probabilities of the trees and branching times and the Brownian-motion process to model the drift of gene frequencies (after a suitable tran...

N = 2 W-supergravity

We quantise the classical gauge theory of N = 2 w ∞-supergravity and show how the underlying N = 2 super-w ∞ algebra gets deformed into an N = 2 super-W ∞ algebra. Both algebras contain the N = 2 super-Virasoro algebra as a subalgebra. We discuss how one can extract from these results information about quantum N = 2 W N-supergravity theories containing a finite number of higher-spin symmetries ...

N=2 Supersymmetric W-algebras

We investigate extensions of the N=2 super Virasoro algebra by one additional super primary field and its charge conjugate. Using a supersymmetric covariant formalism we construct all N=2 super W-algebras up to spin 5/2 of the additional generator. Led by these first examples we close with some conjectures on the classification of N=2 SW(1, ∆) algebras.
