A new proof of the characterization of the weighted Hardy inequality
Bernardis-Medici, Ana Lucía
; Martín-Reyes, Francisco Javier; Ortega-Salvador, Pedro (Cambridge University Press, 2005)
Maz'ja and Sinnamon proved a characterization of the boundedness of the Hardy operator from Lp(v) into Lq(w) in the case 0 < q < p, 1 < p < ∞. We present here a new simple proof of the sufficiency part of that result. -
Automatic feature scaling and selection for support vector machine classification with functional data.
Jiménez-Cordero, María Asunción; Maldonado-Alarcón, Sebastián (Springer Nature, 2020)
Functional Data Analysis (FDA) has become a very important field in recent years due to its wide range of applications. However, there are several real-life applications in which hybrid functional data appear, i.e., data ... -
Hardy operators on weighted amalgams.
Ortega-Salvador, Pedro; Ramírez Torreblanca, Consuelo (Cambridge University Press, 2010-02-04)
We characterize the boundedness of the Hardy operator between weighted amalgams, a problem studied, but not completely solved, by C. Carton-Lebrun, H. P. Heinig and S. C. Hofmann. We also characterize the weighted weak-type ... -
Log-Gaussian Cox Process in Infinite-Dimensional Spaces.
Torres-Signes, Antoni; Frías, María P.; Ruiz-Medina, María D. (American Mathematical Society, 2018)
This paper introduces new results on doubly stochastic Poisson processes, with log-Gaussian Hilbert-valued random intensity (LGHRI), defined from the Ornstein-Uhlenbeck process (O-U process) in Hilbert spaces. Sufficient ... -
Multiresolution approximations and wavelet bases of weighted Lp spaces
Aimar, Hugo; Bernardis-Medici, Ana Lucía; Martín-Reyes, Francisco Javier (Springer, Birkhäuser Verlag, 2003)
We study boundedness and convergence on L p(R n,dμ) of the projection operators P j given by MRA structures with non-necessarily compactly supported scaling function. As a consequence, we prove that if w is a locally ... -
Singular integrals in the Cesàro sense
Bernardis-Medici, Ana Lucía; Martín-Reyes, Francisco Javier (Springer, Birkhäuser Verlag, 2000)
The existence of the singular integral ∫K(x, y)f(y)dy associated to a Calderón-Zygmund kernel where the integral is understood in the principal value sense TF(x)=limε→0+∫|x−y|>εK(x, y)f(y)dy has been well studied. In this ... -
Unifying Chance-Constrained and Robust Optimal Power Flow for Resilient Network Operations.
Uncertainty in renewable energy generation has the potential to adversely impact the operation of electric networks. Numerous approaches to manage this impact have been proposed, ranging from stochastic and chance-constrained ... -
Weighted bilinear Hardy inequalities.
Aguilar-Cañestro, María Isabel; Ortega-Salvador, Pedro; Ramírez Torreblanca, Consuelo (Elsevier, 2012)
We characterize the weights w, w1, w2 such that the weighted bilinear Hardy inequality b a x a f q x a g q w(x)dx 1q C b a f p1w1 1 p1 b a gp2 w2 1 p2 holds for all nonnegative ... -
Weighted inequalities for Cesàro maximal operator in Orlicz spaces.
Ortega-Salvador, Pedro; Ramírez Torreblanca, Consuelo (Cambridge University Press, 2005-04-26)
Let 0 < α ≤ 1 and let M+α be the Cesàro maximal operator of order α defined by In this work we characterize the pairs of measurable, positive and locally integrable functions (u, v) for which there exists a constant C > 0 ...
