New results toward the classification of biharmonic submanifolds in 𝕊n
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012 We prove some new rigidity results for proper biharmonic immer- sions in Sn of the following types: Dupin hypersurfaces; hypersurfaces, both compact and non-compact, with bounded norm of the second fun- damental form; hypersurfaces satisfying intrinsic ...

Geometric properties of Lie hypersurfaces in a complex hyperbolic space [PDF]
, 2019 summary:We study homogeneous real hypersurfaces having no focal submanifolds in a complex hyperbolic space. They are called Lie hypersurfaces in this space. We clarify the geometry of Lie hypersurfaces in terms of their sectional curvatures, the behavior

$F$-thresholds of hypersurfaces [PDF]
Transactions of the American Mathematical Society, 2009 We continue our study of F-thresholds begun in math/0607660 by an in depth analysis of the hypersurface case. We use the D--module theoretic description of generalized test ideals which allows us to show that in any F--finite regular ring the F-thresholds of hypersurfaces are discrete and rational (in math/0607660 the finite type over a field case was ...

Hypersurfaces with pointwise 1-type Gauss map in Lorentz–Minkowski space; 146–161 [PDF]
Proceedings of the Estonian Academy of Sciences, 2009 Hypersurfaces of a LorentzâMinkowski space Ln+1 with pointwise 1-type Gauss map are characterized. We prove that an oriented hypersurface Mq in Ln+1 has pointwise 1-type Gauss map of the first kind if and only if Mq has constant mean curvature and ...

Height estimates and half-space theorems for hypersurfaces in product spaces of the type ℝ×Mn
Anais da Academia Brasileira de Ciências, 2021 We obtain height estimates and half-space theorems concerning a wide class of hypersurfaces immersed into a product space ℝ × M n, the so-called generalized linear Weingarten hypersurfaces, which extends that one having some constant higher order ...

Optimal Gain Selection for the Arbitrary‐Order Homogeneous Differentiator
International Journal of Robust and Nonlinear Control, EarlyView.ABSTRACT Differentiation of noisy signals is a relevant and challenging task. Widespread approaches are the linear high‐gain observer acting as a differentiator and Levant's robust exact differentiator with a discontinuous right‐hand side. We consider the family of arbitrary‐order homogeneous differentiators, which includes these special cases.
