Abstract

We develop a method for obtaining equations for G-minimal conic bundles with an arbitrary number of singular fibres. When the number of singular fibres is equal to 4, 6, or 7, a detailed classification is given, which includes obtaining the equations for minimal conic bundles (S,G) and an explicit indication of the action of the group G on the Picard group Pic(S) and on the surface S itself.Bibliography: 19 titles.
