We study the Hartogs extension phenomenon in noncompact almost homogeneous algebraic varieties, and we prove a cohomological and a weight criterion for the Hartogs phenomenon. In the case of spherical varieties we prove a criterion for the Hartogs phenomenon in terms of coloured fans. Bibliography: 28 titles.
Keywords: Hartogs phenomenon, holomorphic extension, almost homogeneous algebraic variety, spherical variety.
