On the range space of Yano's extrapolation theorem and new extrapolation estimates at infinity.
Given a sublinear operator T satisfying that !Tf!Lp(ν) ≤ C p−1 !f!Lp(µ), for every 1 < p ≤ p0, with C independent of f and p, it was proved in [C] that sup r>0 ! ∞ 1/r λν T f (y) dy 1 + log+ r ! ' M |f(x)|(1 + log+ |f(x)|) ...
Some remarks on the abundance of stable periodic orbits inside homoclinic lobes
We consider a family $F_\epsilon$ of area-preserving maps (APMs) with a hyperbolic point $H_\epsilon$ whose invariant manifolds form a figure-eight and we study the abundance of elliptic periodic orbits visiting homoclinic ...
Equidistribution estimates for Fekete points on complex manifolds
We study the equidistribution of Fekete points in a compact complex manifold. These are extremal point configurations defined through sections of powers of a positive line bundle. Their equidistribution is a known result. ...
A lower bound in Nehari's theorem on the polydisc
By theorems of Ferguson and Lacey ($d=2$) and Lacey and Terwilleger ($d>2$), Nehari's theorem is known to hold on the polydisc $\D^d$ for $d>1$, i.e., if $H_\psi$ is a bounded Hankel form on $H^2(\D^d)$ with analytic symbol ...
Elementary matrix decomposition and the computation of Darmon points with higher conductor
We extend the algorithm of Darmon-Green and Darmon-Pollack for computing $p$-adic Darmon points on elliptic curves to the case of composite conductor. We also extend the algorithm of Darmon-Logan for computing ATR Darmon ...
Multipower variation for Brownian semistationary processes
In this paper we study the asymptotic behaviour of power and multipower variations of processes Y : Yt = Z t 1 g(t s) sW (ds) +Zt
Transfers from the Earth to L2 Halo orbits in the Earth-Moon bicircular problem
This paper deals with direct transfers from the Earth to Halo orbits related to the translunar point. The gravitational influence of the Sun as a fourth body is taken under consideration by means of the Bicircular Problem ...
Interpolation and duality in spaces of pseudocontinuable functions
Given an inner function $\theta$ on the unit disk, let $K_\theta^p:=H^p \cap \theta \bar{z} \overline{H^p}$ be the associated starinvariant subspace of the Hardy space $H^p$. Also, we put $K_{* \theta}:=K_\theta^2 \cap ...
Dynamical effects of loss of cooperation in discrete-time hypercycles
Hypercycles' dynamics have been widely investigated in the context of origins of life, especially using time-continuous dynamical models. Different hypercycle architectures jeopardising their stability and persistence have ...
Corrigendum: An enhanced uncertainty principle for the Vaserstein distance
This article corrects the following: An enhanced uncertainty principle for the Vaserstein distance Tom Carroll, Francesc Xavier Massaneda clares i Joaquim Ortega Cerdà Bulletin of the London Mathematical Society, Volume ...
Appendix to the paper by W. Gubler, Ph. Jell, K. Künnemann and F. Martin, Continuity of plurisubharmonic envelopes in non-archimedean geometry and test ideals
Let L be an ample line bundle on a smooth projective variety $X$ over a non-archimedean field $K$. For a continuous metric on $L^{\text {an }},$ we show In the following two cases that the semipositive envelope is a ...
Darmon points on elliptic curves over number fields of arbitrary signature
We present new constructions of complex and $p$-adic Darmon points on elliptic curves over base fields of arbitrary signature. We conjecture that these points are global and present numerical evidence to support our conjecture.
Stability conditions in families
We develop a theory of Bridgeland stability conditions and moduli spaces of semistable objects for a family of varieties. Our approach is based on and generalizes previous work by Abramovich-Polishchuk, Kuznetsov, Lieblich, ...
Semi-purity of tempered Deligne cohomology
In this paper we define the formal and tempered Deligne cohomology groups, that are obtained by applying the Deligne complex functor to the complexes of formal differential forms and tempered currents respectively. We then ...
Integrating Collaboration and Leadership in Conversational Group Recommender Systems
Recent observational studies highlight the importance of considering the interactions between users in the group recommendation process, but to date their integration has been marginal. In this article, we propose a ...
Left braces of size 8<em>p</em>
We describe all left braces of size $8 p$ for an odd prime $p \neq 3,7$ and validate the number given by Bardakov, Neschadim and Yadav in [2]. We give a characterization for isomorphism classes of a semidirect product of ...
Current and Future Role of Artificial Intelligence in Cardiac Imaging
Cardiovascular disease remains the most common cause of morbidity and mortality worldwide, and thus an important focus for medical research and medical imaging. Despite continuous advances in cardiac imaging modalities, ...
Solución al problema de Cauchy relativo a una cierta familia de ecuaciones en derivadas parciales de tercer orden
Este trabajo no es más que una extensión de otro nuestro anterior, publicado en Collectánea Mathemática (Vol. XIII.-1961), en el sentido de abordar el problema de CAUCHY, relativo a la ecuación de 3.or orden de tipo ...
Unas aplicaciones de un cálculo funcional holomorfo en dimensión infinita.
El cálculo funcional holomorfo sobre álgebras de Banach por funciones holomorfas en espacios de dimensión infinita introducido por L. Waelbroeck (5) se extiende a funciones holomorfas valoradas en un espacio de Banach. ...
Pricing cumulative loss derivatives under additive models via Malliavin calculus
We show that the integration by parts formula based on Malliavin-Skorohod calculus techniques for additive processes helps us to compute quantities like $\mathbb{E}\left(L_{T} h\left(L_{T}\right)\right)$, or more generally ...
