Generalized instantons on complex projective spaces
Journal 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
Anais 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
Differential 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.

Representing stable complexes on projective spaces
Journal 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.

Complex-projective and lens product spaces [PDF]
Boletín 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.

International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary In this contribution, we propose a detailed study of interpolation‐based data‐driven methods that are of relevance in the model reduction and also in the systems and control communities. The data are given by samples of the transfer function of the underlying (unknown) model, that is, we analyze frequency‐response data.

Data‐driven performance metrics for neural network learning
International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

Stable hypersurfaces in the complex projective space [PDF]
Annali 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.
