We classify irreducible homogeneous almost Hermite-Lorentz spaces of complex dimension 3, and prove in particular they are geodesically complete.

In this paper, we consider N, a simply connected two-step nilpotent Lie group with L(N), its
corresponding (two-step nilpotent) Lie algebra, and we study Newton’s method for solving the…

Abstract. A bounded operator S on a Hilbert space is hyponormal if S*S-SS* is positive. In this work we find necessary conditions for the hyponormality of the Toeplitz operaor T_f+g^- on the…
