Monotonicity of discrete spectra of Dirichlet Laplacian in 3-dimensional layers
Fedor Bakharev, Sergey Matveenko
We investigate monotonicity properties of eigenvalues of the Dirichlet Laplacian in polyhedral layers of fixed width. We establish that eigenvalues below the essential spectrum thr…
Fractional Laplacian in bended strip
Fedor Bakharev, Sergey Matveenko
The spectral properties of the restricted fractional Laplacian with Dirichlet boundary conditions in a smoothly bent waveguide is investigated. The existence of eigenvalues below t…
Velocity of viscous fingers in miscible displacement: Intermediate concentration
Fedor Bakharev, Aleksandr Enin, Sergey Matveenko +4
We investigate one-phase flow in porous medium corresponding to a miscible displacement process in which the viscosity of the injected fluid is smaller than the viscosity in the re…
Fractional Laplacian in V-shaped waveguide
Fedor Bakharev, Sergey Matveenko
The spectral properties of the restricted fractional Dirichlet Laplacian in -shaped waveguides are studied. The continuous spectrum for such domains with cylindrical outle…
