A diffeomorphism \(\delta:M\to M\) of a boundaryless \(k\)-dimensional submanifold \(M\) of a Euclidean space \(\mathbb{R}^n\) is called by the authors diametrical with respect to the center \(p\) if \(x\), \(p\) and \(\delta(x)\) \((x\in M)\) are distinct collinear points and \(T_x M=T_{\delta(x)} M\).

Journal of Geometric Analysis, 2011
From the author's abstract: We propose an answer to a question raised by F. Burstall: Is there any interesting theory of isothermic submanifolds of \(\mathbb{R}^n\) of dimension greater than two? We call an \(n\)-immersion \(f(x)\) in \(\mathbb{R}^m\) isothermic\(_k\) if the normal bundle of \(f\) is flat and \(x\) is a line of curvature coordinate ...

The Quarterly Journal of Mathematics, 1997
The second author defined in [\textit{C. Olmos}, J. Differ. Geom. 39, 605-627 (1994; Zbl 0806.53054)] the rank of a homogeneous submanifold of a Euclidean space as the maximal number of locally defined and linearly independent parallel normal vector fields.

The Jump of the Laplacian on a Submanifold
Mathematische Nachrichten, 1997AbstractAssume that a submanifold M ⊂ ℝn of an arbitrary codimension k ϵ {1, …, n} is closed in some open set O→ℝn. With a given function u ϵ C2(O\M) we may associate its trivial extension u: O→ℝ such that u|O\M=u and u|m ≡ 0. The jump of the Laplacian of the function u on the submanifold M is defined by the distribution Δu — Δu.

On the Geometry of Lagrangian Submanifolds
Mathematical Notes, 2001The author proves that an \( s \)-Lagrangian submanifold of a Kähler manifold of constant holomorphic sectional curvature \( c \) is a space of constant curvature \( c/4 \).
