Analogue of Flat Basis and Cohomological Intersection Numbers for General Hypergeometric Functions
[Full Article (PDF)] [MathSciNet Review (HTML)] [MathSciNet Review (PDF)]
Abstract:
The general hypergeometric functions of confluent type given by $1$-dimensional integral are studied. To such functions, the rational de Rham cohomology group is associated and cohomological intersection numbers for a good basis are computed explicitly, using the property of the basis analogous to the flat basis of simple singularity of $ A $-type.
