Existence of multiple solutions for a class of nonhomogeneous problems with critical growth

Electronic Journal of Qualitative Theory of Differential Equations, 2017
In this paper, we study the existence and multiplicity of solutions for $(p_1(x),p_2(x))$-equation with critical growth. The technical approach is mainly based on the variational method combined with the genus theory.

Multiple solutions to the double phase problems involving concave-convex nonlinearities

AIMS Mathematics, 2023
This paper is concerned with several existence results of multiple solutions for Schrödinger-type problems involving the double phase operator for the case of a combined effect of concave-convex nonlinearities.

Multiple solutions of nonlinear boundary value problems with oscillatory solutions

Mathematical Modelling and Analysis, 2006
We consider two second order autonomous differential equations with critical points, which allow the detection of an exact number of solutions to the Dirichlet boundary value problem.

On double phase Kirchhoff problems with singular nonlinearity

Advances in Nonlinear Analysis, 2023
In this paper, we study multiplicity results for double phase problems of Kirchhoff type with right-hand sides that include a parametric singular term and a nonlinear term of subcritical growth.

Stratospheric chemistry: Multiple solutions [PDF]

Geophysical Research Letters, 1979
It is shown that the equations describing chemical partitioning among Clx (HCl, Cl, ClO, ClNO3), NOt (NO, NO2, NO3, N2O5, HNO2, ClNO3) and HOx (OH, HO2) may admit multiple solutions. These solutions apply to the high latitude winter stratosphere where abrupt spatial variations may be expected for NO2, ClO and ClNO3.

Multiple Solutions of Double-Diffusive Convection in Porous Media due to Opposing Heat and Mass Fluxes on Vertical Walls

Journal of Thermal Science and Technology, 2013
The double-diffusive convection in a porous medium due to the opposing heat and mass fluxes on the vertical walls is solved analytically. In the former analysis, we investigated only when ω < π, the parameter arising from a combination among ...

Understanding FBA Solutions under Multiple Nutrient Limitations [PDF]

Metabolites, 2021
Genome-scale stoichiometric modeling methods, in particular Flux Balance Analysis (FBA) and variations thereof, are widely used to investigate cell metabolism and to optimize biotechnological processes. Given (1) a metabolic network, which can be reconstructed from an organism’s genome sequence, and (2) constraints on reaction rates, which may be based
