Geometric Realizations of Hermitian curvature models
M. Brozos-Vazquez, P. Gilkey, H. Kang +1
We show that a Hermitian algebraic curvature model satisfies the Gray identity if and only if it is geometrically realizable by a Hermitian manifold. Furthermore, such a curvature…
Riemannian geometric realizations for Ricci tensors of generalized algebraic curvature operators
P. Gilkey, S. Nikcevic, D. Westerman
We examine questions of geometric realizability for algebraic structures which arise naturally in affine and Riemannian geometry. Suppose given an algebraic curvature operator R at…
Geometric realizations of generalized algebraic curvature operators
P. Gilkey, S. Nikcevic, D. Westerman
We study the 8 natural GL equivariant geometric realization questions for the space of generalized algebraic curvature tensors. All but one of them is solvable; a non-zero projecti…
Geometric realizations of curvature models by manifolds with constant scalar curvature
M. Brozos-Vazquez, P. Gilkey, H. Kang +2
We show any Riemannian curvature model can be geometrically realized by a manifold with constant scalar curvature. We also show that any pseudo-Hermitian curvature model, para-Herm…
Geometrical representations of equiaffine curvature operators
Peter B. Gilkey, Stana Nikcevic
We examine geometric representability results for various classes of equiaffine curvature operators. We show every Ricci flat algebraic curvature operator is geometrically realizab…
