Differential characters and the Steenrod squares

Kiyonori Gomi

The groups of differential characters of Cheeger and Simons admit a natural multiplicative structure. The map given by the squares of degree 2k differential characters reduces to a…

Reduction of strongly equivariant bundle gerbes with connection and curving

Kiyonori Gomi

From a certain strongly equivariant bundle gerbe with connection and curving over a smooth manifold on which a Lie group acts, we construct under some conditions a bundle gerbe wit…

Relationship between equivariant gerbes and gerbes over the quotient space

Kiyonori Gomi

By means of cohomology groups, we study relationships between equivariant gerbes with connection over a manifold with a Lie group action and gerbes with connection over the quotien…

Equivariant smooth Deligne cohomology

Kiyonori Gomi

On the basis of Brylinski's work, we introduce a notion of equivariant smooth Deligne cohomology group, which is a generalization of both the ordinary smooth Deligne cohomology and…

Connections and curvings on lifting bundle gerbes

Kiyonori Gomi

We construct a connection and a curving on a bundle gerbe associated with lifting a structure group of a principal bundle to a central extension. The construction is based on certa…

Gerbes in classical Chern-Simons theory

Kiyonori Gomi

We construct geometrically a gerbe assigned to a connection on a principal SU(2)-bundle over an oriented closed 1-dimensional manifold. If the connection is given by the restrictio…
