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.
