Strichartz estimates for Baouendi–Grushin operators

Revista Matemática Iberoamericana
We prove Strichartz estimates for a class of Baouendi–Grushin operators acting either on the Euclidean space or on a product of the type \mathbb{R}^{d_1}\times M , where (M,g)

Inverse Coefficient Problem for Grushin-Type Parabolic Operators [PDF]

, 2014
The approach to Lipschitz stability for uniformly parabolic equations introduced by Imanuvilov and Yamamoto in 1998 based on Carleman estimates, seems hard to apply to the case of Grushin-type operators studied in this paper. Indeed, such estimates are still missing for parabolic operators degenerating in the interior of the space domain. Nevertheless,

Pullback attractors for non-autonomous parabolic equations involving Grushin operators

Electronic Journal of Differential Equations, 2010
Using the asymptotic a priori estimate method, we prove the existence of pullback attractors for a non-autonomous semilinear degenerate parabolic equation involving the Grushin operator in a bounded domain.

Hardy's inequalities for Grushin operator and Hermite multipliers on Modulation spaces

, 2021
This thesis consists of two broad themes. First one revolves around the Hardy's inequalities for the fractional power of Grushin operator $\G$ which is chased via two different approaches.

Bifurcation and multiplicity results for critical problems involving the p-Grushin operator

Advances in Nonlinear Analysis
In this article, we prove a bifurcation and multiplicity result for a critical problem involving a degenerate nonlinear operator Δγp{\Delta }_{\gamma }^{p}. We extend to a generic p>1p\gt 1 a result, which was proved only when p=2p=2. When p≠2p\ne 2, the

Exploring the conformational changes of the Munc18‐1/syntaxin 1a complex

Protein Science, Volume 33, Issue 3, March 2024.
Abstract Neurotransmitters are released from synaptic vesicles, the membrane of which fuses with the plasma membrane upon calcium influx. This membrane fusion reaction is driven by the formation of a tight complex comprising the plasma membrane N‐ethylmaleimide‐sensitive factor attachment receptor (SNARE) proteins syntaxin‐1a and SNAP‐25 with the ...

Improved Hardy inequalities in the Grushin plane [PDF]

, 2012
We show the Hardy inequality for Grushin operator like ∂x2+4x2∂y2 on a bounded domain Ω⊂R2 can be refined by adding remainder terms such as the improvement of Brezis–Vázquez, Vazquez–Zuazua and Filippas ...

The p-Laplace equation in a class of Hormander vector fields

Electronic Journal of Differential Equations, 2019
We find the fundamental solution to the p-Laplace equation in a class of Hormander vector fields that generate neither a Carnot group nor a Grushin-type space. The singularity occurs at the sub-Riemannian points, which naturally corresponds to finding

Quantitative spectral inequalities for the anisotropic Shubin operators and applications to null-controllability

Comptes Rendus. Mathématique
We prove quantitative spectral inequalities for the (anisotropic) Shubin operators on the whole Euclidean space, thus relating for functions from spectral subspaces associated to finite energy intervals their $L^2$-norm on the whole space to the $L^2 ...
