Harmonic vibration of cusped plates in the N-th approximation of Vekua’s hierarchical models
In this paper elastic cusped symmetric prismatic shells (i.e., plates of variable thickness with cusped edges) in the N-th approximation of Vekua’s hierarchical models are considered.

Rodingite‐Derived Melt as a Recipe for Ultra‐Calcic Magmas
Abstract Rodingite is a high‐CaO rock formed by Ca‐rich fluid metasomatism on mafic protoliths. It typically occurs within serpentinite and represents an often‐overlooked constituent of the altered oceanic lithosphere that may be subducted into the mantle.

On Compressible Fluid Flows of Forchheimer‐Type in Rotating Heterogeneous Porous Media
ABSTRACT We study the dynamics of compressible fluids in rotating heterogeneous porous media. The fluid flow is of Forchheimer‐type and is subject to a mixed mass and volumetric flux boundary condition. The governing equations are reduced to a nonlinear partial differential equation for the pseudo‐pressure.

Gain of regularity for a Korteweg - de Vries - Kawahara type equation
We study the existence of local and global solutions, and the gain of regularity for the initial value problem associated to the Korteweg - de Vries - Kawahara (KdVK) equation perturbed by a dispersive term which appears in several fluids dynamics ...

To a nonlocal generalization of the Dirichlet problem
A mixed problem with a boundary Dirichlet condition and nonlocal integral condition is considered for a two-dimensional elliptic equation.The existence and uniqueness of a weak solution of this problem are proved in a weighted Sobolev space.

Existence results for Navier problems with degenerated (p,q)-Laplacian and (p,q)-Biharmonic operators [PDF]
In this article, we prove the existence and uniqueness of solutions for the Navier problem \[ (P)\left\{ \begin{array}{llll} & {\Delta}{\big[}{\omega}(x)(\,{\vert{\Delta}u\vert}^{p-2}{\Delta}u + {\vert{\Delta}u\vert}^{q-2}{\Delta}u ...

Hardy-Sobolev inequalities and weighted capacities in metric spaces
Let $\Omega$ be an open set in a metric measure space $X$. Our main result gives an equivalence between the validity of a weighted Hardy–Sobolev inequality in $\Omega$ and quasiadditivity of a weighted capacity with respect to Whitney covers of $\Omega$.

Maximal estimates for fractional Schr\"odinger equations with spatial variable coefficient
Let $v(r,t)=\mathcal{T}_tv_0(r)$ be the solution to a fractional Schrodinger equation where the coefficient of Laplacian depends on the spatial variable. We prove some weighted $L^q$ estimates for the maximal operator generated by $\mathcal{T}_t$ with
