Hardy inequalities for Landau Hamiltonian and for Baouendi-Grushin operator with Aharonov-Bohm type magnetic field. Part I

, 2019
In this paper we prove the Hardy inequalities for the quadratic form of the Laplacian with the Landau Hamiltonian type magnetic field. Moreover, we obtain a Poincaré type inequality and inequalities with more general families of weights.

Bilinear Bochner-Riesz Means for Grushin Operators

This paper is devoted to the study of $L^{p_1} \times L^{p_2}$ to $L^{p}$ boundedness of the bilinear Bochner-Riesz mean $\mathcal{B}^α$ associated with the Grushin operator $\mathcal{L} = -Δ_{x'} - |x'|^2 Δ_{x''}$ on $\mathbb{R}^{d_1} \times \mathbb{R}^{d_2}$.

A Note on Nonlinear Critical Problems Involving the Grushin Subelliptic Operator: Bifurcation and Multiplicity Results

We consider the boundary value problem (Formula presented.) where λ>0, Ω is an open bounded domain in RN, N≥3, with 0∈Ω ̄, while Δγ is the Grushin operator (Formula presented.) We prove a multiplicity and bifurcation result for this problem, extending ...

ON THE TRANSITION DENSITY FUNCTION OF THE DIFFUSION PROCESS GENERATED BY THE GRUSHIN OPERATOR

The short-time asymptotic behavior of the transition density function of the diffusion process generated by the Grushin operator with parameter γ > 0 will be investigated, by using its explicit expression in terms of expectation.

Uniform heat kernel asymptotics for the Grushin operator

Adopting the powerful methods introduced in \cite{li2021carnotcaratheodory, LZ2025}, we investigate the asymptotic behaviour at infinity for the heat kernel associated with the Grushin operator $Δ_G = Δ_x + |x|^2 Δ_u$ on $ \mathbb{R}_x ^n \times \mathbb{R}_u ^{n'} $ for all $ n , \, n' \ge 1 $.
