Multilinear fractional integral operators on non-homogeneous metric measure spaces [PDF]

open access: yesJournal of Inequalities and Applications, 2016
En este trabajo, se obtiene la delimitación en espacios de Lebesgue para operadores integrales fraccionarios multilineales y conmutadores generados por integrales fraccionarias multilineales con una función $\operatorname{RBMO}(\mu)$ en espacios de medida métrica no homogéneos.

Renormalization group properties in the conformal sector: towards perturbatively renormalizable quantum gravity

open access: yesJournal of High Energy Physics, 2018
The Wilsonian renormalization group (RG) requires Euclidean signature. The conformal factor of the metric then has a wrong-sign kinetic term, which has a profound effect on its RG properties.

Boundedness of Marcinkiewicz integrals on Hardy spaces H^p over non-homogeneous metric measure spaces [PDF]

open access: yesJournal of Mathematical Inequalities, 2018
Summary: Under the assumption that \((\mathcal{X}, d, \mu)\) is a non-homogeneous metric measure space, the authors prove that the Marcinkiewicz integral operator is bounded from the molecular Hardy space \(\tilde{H}_{mb,\rho}^{p,q\gamma,\varepsilon}(\mu)\)(or the atomic Hardy space \(\tilde{H}_{atb,\rho}^{p,q,\gamma}(\mu))\) into the Lebesgue space ...

Commutators of multilinear $ \theta $-type generalized fractional integrals on non-homogeneous metric measure spaces

open access: yesAIMS Mathematics, 2022
<abstract><p>Let $ {\mathcal{I}_{\alpha, m}} $ be the multilinear $ \theta $-type generalized fractional integrals and $ \vec{b}_{\sigma} $ be the vector with each $ b_{\sigma_{i}} \in \widetilde{{\rm{RBMO}}}\left(\mu\right) $. The boundedness for $ {\mathcal{I}_{\alpha, m}} $ and the iterated multi-commutators $ {\mathcal{I}_{\alpha, m ...

Vector-valued non-homogeneous $Tb$ theorem on metric measure spaces

open access: yesRevista Matemática Iberoamericana, 2012
We prove a vector-valued non-homogeneous Tb theorem on certain quasimetric spaces equipped with what we call an upper doubling measure. Essentially, we merge recent techniques from the domain and range side of things, achieving a

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
