EBIHARA, M.: Some remarks on infinitesimal deformations of a conic bundle I
Saitama Mathematical Journal 2000(Vol. 18) pp.1-21
Abstract
This paper is the first part of a study of infinitesimal deformations of a
conic bundle of dimension three.
We especially discuss the relationship between the infinitesimal
deformations of a conic bundle and the infinitesimal displacements of
its discriminant locus.
