A unifying framework for -statistics, polykays and their multivariate generalizations
Elvira Di Nardo, Giuseppe Guarino, Domenico Senato
Through the classical umbral calculus, we provide a unifying syntax for single and multivariate -statistics, polykays and multivariate polykays. From a combinatorial point of vi…
On the curvature groups of a CR manifold
Elisabetta Barletta, Sorin Dragomir
We show that any contact form whose Fefferman metric admits a nonzero parallel vector field is pseudo-Einstein of constant pseudohermitian scalar curvature. As an application we co…
On the boundary behavior of the holomorphic sectional curvature of the Bergman metric
Elisabetta Barletta
We obtain a conceptually new differential geometric proof of P.F. Klembeck's result that the holomorphic sectional curvature of a strictly pseudoconvex domain approaches (in the bo…
On the pseudohermitian sectional curvature of a strictly pseudoconvex CR manifold
Elisabetta Barletta
We study the pseudohermitian sectional curvature of a CR manifold.
Jacobi fields of the Tanaka-Webster connection on Sasakian manifolds
Elisabetta Barletta, Sorin Dragomir
We build a variational theory of geodesics of the Tanaka-Webster connection on a strictly pseudoconvex CR manifold.
Minimality in CR geometry and the CR Yamabe problem on CR manifolds with boundary
Sorin Dragomir
We study the minimality of an isometric immersion of a Riemannian manifold into a strictly pseudoconvex CR manifold endowed with the Webster metric hence formulate a version of the…
