Generalized instantons on complex projective spaces

open access: yesJournal of Mathematical Physics, 2009
We study a class of generalized self-duality relations in gauge theories on the complex projective space with the Fubini–Study metric. Our theories consist of only gauge fields with gauge group U(n). The pseudoenergies which we consider contain higher orders of field strength and are labeled by an integer p smaller than or equal to [n/2].

On the geometry of Poincaré's problem for one-dimensional projective foliations

open access: yesAnais da Academia Brasileira de Ciências, 2001
We consider the question of relating extrinsic geometric characters of a smooth irreducible complex projective variety, which is invariant by a one-dimensional holomorphic foliation on a complex projective space, to geometric objects associated to the ...

On projective invariants of the complex Finsler spaces

open access: yesDifferential Geometry and its Applications, 2012
In this paper the projective curvature invariants of a complex Finsler space are obtained. By means of these invariants the notion of complex Douglas space is then defined. A special approach is devoted to obtain the equivalence conditions that a complex Finsler space should be Douglas.

On the dynamics characterization of complex projective spaces [PDF]

open access: yesJournal of Fixed Point Theory and Applications, 2020
We show that a closed weakly-monotone symplectic manifold of dimension $2n$ which has minimal Chern number greater than or equal to $n+1$ and admits a Hamiltonian toric pseudo-rotation is necessarily monotone and its quantum homology is isomorphic to that of the complex projective space. As a consequence when $n=2$, the manifold is symplectomorphic to $

Complex-projective and lens product spaces [PDF]

open access: yesBoletín de la Sociedad Matemática Mexicana, 2014
Let $t$ be a positive integer. Following work of D. M. Davis, we study the topology of complex-projective product spaces, i.e. quotients of cartesian products of odd dimensional spheres by the diagonal $S^1$-action, and of the $t$-torsion lens product spaces, i.e.

Representing stable complexes on projective spaces

open access: yesJournal of Algebra, 2014
We give an explicit proof of a Bogomolov-type inequality for $c_3$ of reflexive sheaves on $\mathbb{P}^3$. Then, using resolutions of rank-two reflexive sheaves on $\mathbb{P}^3$, we prove that some strata of the moduli of rank-two complexes that are both PT-stable and dual-PT-stable are quotient stacks.

FORMATION OF MODERN MATHEMATICAL APPROACH TO SOLVING PROBLEMS OF PHYSICS

open access: yesФізико-математична освіта, 2022
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

Complexity of triangulations of the projective space

open access: yesTopology and its Applications, 2003
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.

Stable hypersurfaces in the complex projective space [PDF]

open access: yesAnnali di Matematica Pura ed Applicata (1923 -), 2019
We characterize the sphere with radius $$\tan ^2 r = 2n+1$$ in the complex projective space $${{\mathbf {C}}}P^{n}$$ as the unique stable hypersurface subject to certain bounds on the curvatures.
