The Bargmann-Wigner Equations in Spherical Space

D. G. C. McKeon, T. N. Sherry

The Bargmann-Wigner formalism is adapted to spherical surfaces embedded in three to eleven dimensions. This is demonstrated to generate wave equations in spherical space for a vari…

A model structure a la Thomason on 2-Cat

K. Worytkiewicz, K. Hess, P. E. Parent +1

We exhibit a model structure on 2-Cat, obtained by transfer from sSet across the adjunction C_2 o Sd^2 -| Ex^2 o N_2.

Cup Products in Hopf-Cyclic Cohomology

Masoud Khalkhali, Bahram Rangipour

We construct cup products of two different kinds for Hopf-cyclic cohomology. When the Hopf algebra reduces to the ground field our first cup product reduces to Connes' cup product…

Magnetic Fields in Molecular Cloud Cores

Shantanu Basu

Observations of magnetic field strengths imply that molecular cloud fragments are individually close to being in a magnetically critical state, even though both magnetic field and…

The renormalization group improved effective potential in massless models

F. T. Brandt, F. A. Chishtie, D. G. C. McKeon

The effective potential is considered in massless theory. The expansion of in powers of the coupling and of the logarithm of the background field is reorga…

Fibred sites and stack cohomology

J. F. Jardine

The usual notion of a site fibred over a stack is expanded to a definition of a site C/A fibred over a presheaf of categories A. Presheaves of simplicial sets on the site fibred ov…
