Isometric immersions of Riemannian manifolds in $k$ -codimensional Euclidean space

Dan Gregorian Fodor

We use a new method to give conditions for the existence of a local isometric immersion of a Riemannian $n$ -manifold $M$ in $R^{n + k}$ , for a given $n$ and $k$ . These equat…

Algebraic conditions for the positivity of sectional curvature

Dan Gregorian Fodor

We examine algebraic conditions for the sectional positivity of the Riemann curvature operator. We describe sufficient conditions for dimension $n = 4$ , and complete characterization…
