Abstract: | An approach for the investigation of the geometry of (2n+1) -webs in 2n-dimensional affinely connected spaces A2n by means of the prolonged differentiation is given in 1] Using this approach in the present paper some properties of (2n+1)-webs in A2n are studied. Necessary and sufficient conditions under which the generalized affinor of Hess of a (2n+1)-web is covariantly constant are found. The space A2n, containing a (2n+1)-web with a constant covariant generalized affinor of Hess, is determined. Conditions for geodesicity of the lines of a given (2n+1)-web in A2n in terms of its tensor are found, also.The present investigation is partially supported by the Ministry of Science and Higher Education of People's Republic of Bulgaria under grant 1021. |
