Estimates for critical groups of solutions to quasilinear elliptic systems

Electronic Journal of Differential Equations, 2003
In this work we study a class of functionals, defined on Banach spaces, associated with quasilinear elliptic systems. Firstly, we prove some regularity results about the critical points of such functionals and then we estimate the critical groups in each

Critical swimming speed in groups of Atlantic salmon Salmo salar

Aquaculture Environment Interactions, 2016
Critical swimming speed (Ucrit) has traditionally been measured in relatively small swimming tunnels with 1 fish alone. However, both increased flume lengths and swimming in groups are known to improve performance.

Resonant (p,q)-equations with Robin boundary condition

Electronic Journal of Differential Equations, 2018
We consider a nonlinear nonhomogeneous Robin problem that has the sum of a p-Laplacian and a q-Laplacian (a (p,q)-equation). The reaction term is a Caratheodory function which is resonant at $\pm\infty$ with respect to any nonprincipal variational ...

Multiplicity results for the Kirchhoff type equation via critical groups

Boundary Value Problems, 2018
In this paper, we will compute critical groups at zero for the Kirchhoff type equation using the property that critical groups are invariant under homotopies preserving isolatedness of critical points.

Existence and multiplicity of solutions for a class of superlinear p-Laplacian equations

Advances in Nonlinear Analysis
In this work, we investigate a class of pp-Laplacian equations with the Dirichlet boundary condition. Under some new conditions, the existence and multiplicity of nontrivial solutions are proved by means of the variational methods.

Existence of nontrivial solutions for a class of biharmonic equations with singular potential in RN $\mathbb{R}^{N}$

Boundary Value Problems, 2018
In this paper, we study a class of biharmonic equations with a singular potential in RN $\mathbb{R}^{N}$. Under appropriate assumptions on the nonlinearity, we establish some existence results via the Morse theory and variational methods.
