"This book describes how to use quaternions and spinors to study conformal immersions of Riemann surfaces into R[superscript 3]. The first part develops the necessary quaternionic calculus on surfaces, its application to surface theory and the study of conformal immersions and s…
This work defines the higher spinor classes of an orthogonal representation of a Galois group. These classes are higher-degree analogues of the Fröhlich spinor class, which quantify the difference between the Stiefel-Whitney classes of an orthogonal representation and the Hasse-…
This conference brought together physicists and mathematicians working on spinors, which have played an important role in recent research on supersymmetry, Kaluza-Klein theories, twistors and general relativity.
