Almost Extrinsically Homogeneous Submanifolds of Euclidean Space [PDF]
, 2018 Consider a closed manifold M immersed in Rm. Suppose that the trivial bundle M × Rm = T M ⊗ ν M is equipped with an almost metric connection ~ ∇ which almost preserves the decomposition of M × Rm into the tangent and the normal bundle.

A note on the l^2-norm of the second fundamental form of algebraic manifolds [PDF]
, 2010 2000 Mathematics Subject Classification: 53C42, 53C55.Let M f → CP^n be an algebraic manifold of complex dimension d and let σf be its second fundamental form. In this paper we address the following conjecture, which is the analogue of the one stated by

From Frustration to Understanding: An Inquiry into Secondary Mathematics Teachers’ Experiences with Government Mandated Examinations [PDF]
, 2014 The purpose of this study was to develop an understanding of secondary mathematics teachers’ experiences in a context of government-mandated examinations (GMEs). Having had my own experiences teaching mathematics courses where students wrote a GME, I had

Homogeneous two-manifolds with an invariant two-form
, 2007 : We study a 2-dimensional manifold that is homogeneous acted on by a 3-dimensional Lie group G, and that has a 2-form invariant under G. We show that such a manifold can be realized as a surface in the affine 3-space and list such realizations ...

Some Results about the Classification of Totally Real Minimal Surfaces in S
, 2007 In this paper we prove that the Contact angle (π/4 ≤ β < π/2) for totally real compact minimal surfaces in the sphere S 5 with a parallel normal vector field must be constant.

Complete maximal spacelike surfaces in an anti-de Sitter space {\bf H}^{4}_{2}(c)
, 2000 In this paper, we prove that if M^2 is a complete maximal spacelike surface of an anti-de Sitter space {\bf H}^{4}_{2}(c) with constant scalar curvature, then S=0, S={-10c\over 11}, S={-4c\over 3} or S=-2c, where S is the squared norm of the second ...
