Symmetries and reversing symmetries of polynomial automorphisms of the plane
The polynomial automorphisms of the affine plane over a field K form a group
which has the structure of an amalgamated free product. This well-known
algebraic structure can be used to determine some key results about the
symmetry and reversing symmetry groups of a given polynomial automorphism.Comment: 27 pages, AMS-Late
The structure of reversing symmetry groups
We present some of the group theoretic properties of reversing symmetry
groups, and classify their structure in simple cases that occur frequently in
several well-known groups of dynamical systems.Comment: 12 page
Fractionation of human immune γ-globulin
Equine and bovine serum proteins have recently been fractionated by means of a physical method utilizing an electrophoretic adaptation of the principles of the Clusius column (l-4), first described and tested by Kirkwood (5) and Nielsen (6). The method of electrophoresis-convection has now been applied to the fractionation of human γ-globulin. The γ-globulin was prepared by ethanol fractionation (7) from the plasma of individuals hyperimmunized to Hemophilus pertussis organisms. The resulting fractions of γ-globulin have been characterized electrophoretically, and the protective antibody activity and agglutinin titer have been measured
