We construct infinite families of regular normal Cartan geometries with nonvanishing curvature and essential automorphisms on closed manifolds for many higher rank parabolic model geometries. To do this, we use particular elements the kernel Kostant Laplacian to homogeneous desired type, giving a global realization an elegant local construction due Kruglikov The, then modify these make their ba...

background: the purpose of this study was to compare patient delay, diagnosis delay and treatment delay in breast cancer patients of selected public and private health centers in tehran, iran. methods: in this cross-sectional study, female patients with newly diagnosed breast cancer in a public medical complex and a private breast clinic within one year were included. patient delay was consider...

Suppose 2n + 1 ≥ p + q. In an earlier paper in 2000 we study a certain sesquilinear form (, )π introduced by Jian-Shu Li in 1989. For π in the semistable range of θ(MO(p, q) → MSp2n(R)), if (, )π does not vanish, then it induces a sesquilinear form on θ(π). In another work in 2000 we proved that (, )π is positive semidefinite under a mild growth condition on the matrix coefficients of π. In thi...

Let X be an even dimensional symmetric bilinear space defined over a totally real number field F with adeles A, and let σ = ⊗vσv be an irreducible tempered cuspidal automorphic representation of O(X,A). We give a sufficient condition for the nonvanishing of the theta lift Θn(σ) of σ to the symplectic group Sp(n,A) (2n by 2n matrices) for 2n ≥ dimX for a large class of X. As a corollary, we show...
