Real hypersurfaces and complex submanifolds in complex projective space [PDF]

Transactions of the American Mathematical Society, 1986
Let M M be a real hypersurface in P n ( C ) {P^n}({\mathbf {C}}) be the complex structure and ξ \xi denote a unit normal vector field on M M .

Peptide‐based ligand antagonists block a Vibrio cholerae adhesin

FEBS Letters, EarlyView.
The structure of a peptide‐binding domain of the Vibrio cholerae adhesin FrhA was solved by X‐ray crystallography, revealing how the inhibitory peptide AGYTD binds tightly at its Ca2+‐coordinated pocket. Structure‐guided design incorporating D‐amino acids enhanced binding affinity, providing a foundation for developing anti‐adhesion therapeutics ...

Toeplitz Operators, Pseudo-Homogeneous Symbols, and Moment Maps on the Complex Projective Space

Journal of Function Spaces, 2017
Following previous works for the unit ball due to Nikolai Vasilevski, we define quasi-radial pseudo-homogeneous symbols on the projective space and obtain the corresponding commutativity results for Toeplitz operators. A geometric interpretation of these

Mechanisms of parasite‐mediated disruption of brain vessels

FEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Quadratic Killing tensors on symmetric spaces which are not generated by Killing vector fields

Comptes Rendus. Mathématique
Every Killing tensor field on the space of constant curvature and on the complex projective space can be decomposed into the sum of symmetric tensor products of Killing vector fields (equivalently, every polynomial in velocities integral of the geodesic ...

One-dimensional super Calabi-Yau manifolds and their mirrors

Journal of High Energy Physics, 2017
We apply a definition of generalised super Calabi-Yau variety (SCY) to supermanifolds of complex dimension one. One of our results is that there are two SCY’s having reduced manifold equal to ℙ 1 $$ {\mathrm{\mathbb{P}}}^1 $$ , namely the projective ...

Spaces of algebraic maps from real projective spaces into complex projective spaces

, 2008
We study the homotopy types of spaces of algebraic (rational) maps from real projective spaces into complex projective spaces. In a previous paper we have shown that the inclusion of the first space into the second one is a homotopy equivalence. In this paper we prove that the homotopy types of the terms of the natural "degree" filtration approximate ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Symmetries of Homotopy Complex Projective Three Spaces [PDF]

Transactions of the American Mathematical Society, 1993
The author considers symmetries of six-dimensional, smooth, closed manifolds which are homotopy equivalent to \(\mathbb{C} P^ 3\). There are infinitely many differentiably distinct such manifolds. It is known that if \(m\) is an odd prime, infinitely many homotopy \(\mathbb{C} P^ 3\)'s admit \(\mathbb{Z}_ m\) actions whereas only the standard \(\mathbb{
