Nowhere minimal CR submanifolds and Levi-flat hypersurfaces

Journal of Geometric Analysis, 2007
A local uniqueness property of holomorphic functions on real-analytic nowhere minimal CR submanifolds of higher codimension is investigated. A sufficient condition called almost minimality is given and studied.

Local Conditions for Triangulating Submanifolds of Euclidean Space [PDF]

Discrete & Computational Geometry, 2020
AbstractWe consider the following setting: suppose that we are given a manifold M in $${\mathbb {R}}^d$$ R d with positive reach. Moreover assume that we have an embedded simplical complex $${\mathcal {A}}$$

Higher-rank tensor non-Abelian field theory: Higher-moment or subdimensional polynomial global symmetry, algebraic variety, Noether's theorem, and gauging

Physical Review Research, 2021
With a view toward a fracton theory in condensed matter, we introduce a higher-moment polynomial degree-p global symmetry, acting on complex scalar/vector/tensor fields (e.g., ordinary or vector global symmetry for p=0 and p=1 respectively).

Principal Polynomial Nonlinear Process Fault Detection Based on Neighborhood Preserving Embedding

Shanghai Jiaotong Daxue xuebao, 2021
Aimed at the problem of high dimension and nonlinearity of variable data in chemical process, a process fault detection algorithm based on neighborhood preserving embedding(NPE )-principal polynomial analysis (PPA) is proposed in this paper.

Automorphisms of Submanifolds

Advances in Difference Equations, 2010
The paper deals with local symmetries of the infinite-order jet space of C∞-smooth n-dimensional submanifolds in ℝm+n. Transformations under consideration are the most general possible.

Semi-Slant Submanifolds of a Locally Product Manifold [PDF]

gmj, 2005
Abstract In the present paper, we define and study the slant, bi-slant and semi-slant submanifolds of a locally product manifold. We give some characterization theorems for slant submanifolds and semi-slant submanifolds. Moreover, we obtain integrability conditions for the distributions which are involved in the definition of semi-slant ...

Localization for Invariant Submanifolds [PDF]

Mathematical Research Letters, 2001
Let \( M \) be a smooth manifold with an equivariant formal circle action and \( W \) an invariant submanifold of \( M \) which does not contain the fixed points of the action. The author presents a new localization theorem which expresses the integration over \( W/S ^1 \) in terms of the integration over the set of fixed points of the action.
