Keywords:General Schwarz Lemmas, Pseudo-Hermitian Manifolds, Hermitian Manifolds, CR Maps, Transversally Holomorphic Maps
Abstract:
      From the viewpoint of differential geometry, Schwarz lemmas of distance-decreasing type and volume-decreasing type can be obtained by the estimates of sum functions and product functions of all eigenvalues of holomorphic maps. This paper investigates general Schwarz lemmas by estimating partial sum functions and partial product functions of the eigenvalues of generalized holomorphic maps between pseudo-Hermitian manifolds and Hermitian manifolds.
