The Grassmann manifold is the set of all -dimensional planes of an -dimensional projective space, with dim. One of the submanifolds of the Grassmann manifold is a complex of -planes if the dimension of the complex exceeds the difference .

Rational homotopy type of projectivization of the tangent bundle of certain spaces [PDF]
PurposeThe paper aims to determine the rational homotopy type of the total space of projectivized bundles over complex projective spaces using Sullivan minimal models, providing insights into the algebraic structure of these spaces.Design/methodology ...

Nondeformability of the complex projective space.
A proof for the following conjecture of Kodaira and Spencer is given: Let \(\Delta\) be the open unit disk in \({\mathbb{C}}\) and let \(\pi\) : \(M\to \Delta\) be a holomorphic family of compact complex manifolds such that \(\pi^{- 1}(t)\) is biholomorphic to \({\mathbb{P}}_ n\) for \(t\in \Delta -0\).

Complexity of triangulations of the projective space
It is known that any two triangulations of a compact 3-manifold are related by finite sequences of certain local transformations. We prove here an upper bound for the length of a shortest transformation sequence relating any two triangulations of the 3-dimensional projective space, in terms of the number of tetrahedra.

FORMATION OF MODERN MATHEMATICAL APPROACH TO SOLVING PROBLEMS OF PHYSICS
Formulation of the problem. Precision studies of the Higgs boson, supersymmetric particles, the magnetic moment of the muon, electric dipole moment of the electron, flavor anomalies demonstrate the deviation beyond Standard Model. They are connected with

We introduce a notion of normal form for transversely projective structures of singular foliations on complex manifolds. Our first main result says that this normal form exists and is unique when ambient space is two-dimensional.

On the bordism ring of complex projective space [PDF]
The bordism ring M U ∗ ( C P ∞ ) M{U_\ast }(C{P^\infty }) is central to the theory of formal groups as applied by D. Quillen, J. F. Adams, and others recently to complex cobordism. In the present paper,

Noncommutative complex geometry of the quantum projective space
We define holomorphic structures on canonical line bundles of the quantum projective space $\qp^{\ell}_q$ and identify their space of holomorphic sections. This determines the quantum homogeneous coordinate ring of the quantum projective space.

Strongly not relatives Kähler manifolds
In this paper we study Kähler manifolds that are strongly not relative to any projective Kähler manifold, i.e. those Kähler manifolds that do not share a Kähler submanifold with any projective Kähler manifold even when their metric is rescaled by the ...

Complex-variable chaotic systems (CVCSs) have numerous advantages over real-variable chaotic systems in chaos communication due to their increased unpredictability, confidentiality, and the ease of implementation.
