In this paper, we prove that if a metric measure space satisfies the volume doubling condition and the Caffarelli–Kohn–Nirenberg inequality with the same exponent $$n(n\ge 2)$$ , then it has exactly n-dimensional volume growth. As application, we

We consider the pseudo-Euclidean space $$(\mathbb {R}^n,g)$$ , $$n \ge 3$$ , with coordinates $$x=\left( x_1,...,x_n\right) $$ and metric components $$g_{ij} = \delta _{ij}\epsilon _i$$ , $$1\le i, j\le n$$ , where $$\varepsilon _i=\pm 1$$ , with at

In this paper, we study gradient Einstein-type structure immersed into a Riemannian warped product manifold. We obtain some triviality results for the potential function and smooth map $u$. We investigate conditions for a gradient Einstein-type struc

In this paper, we investigate the eigenvalue problem of the Markov diffusion operator $$\mathfrak {L}$$ and $$\mathfrak {L}^2$$ , respectively. Firstly, we obtain some general inequalities for eigenvalues of the operator $$\mathfrak {L}$$ and $$\math

Let \(\Omega \) be a bounded domain in a n-dimensional Euclidean space \(\mathbb {R}^{n}\). We study eigenvalues of an eigenvalue problem of a system of elliptic equations of the drifting Laplacian $$\begin{aligned} \left\{ \begin{array}{ll} \mathbb

The purpose of this article is to study gradient Yamabe soliton on warped product manifolds. First, we prove triviality results in the case of noncompact base with limited warping function, and for compact base. In order to provide nontrivial example

In this paper, we study eigenvalues of polydrifting Laplacian on compact Riemannian manifolds with boundary (possibly empty). Here, we prove a universal inequality for the eigenvalues of the polydrifting operator on compact domains in an Euclidean sp

In the Euclidean space ( R n , g ) , with n ≥ 3 , g i j = δ i j , we consider a diagonal ( 0 , 2 ) -tensor T = ∑ i f i ( x ) d x i 2 . We obtain necessary and sufficient conditions for the existence of a metric g ¯ , conformal to g, such that R
