Boundary-value problems for the biharmonic equation with a linear parameter
Electronic journal of differential equations, Tome 2002 (2002)
We consider two boundary-value problems for the equation

$ \Delta^2 u(x,y)-\lambda \Delta u(x,y)=f(x,y) $

with a linear parameter on a domain consisting of an infinite strip. These problems are not elliptic boundary-value problems with a parameter and therefore they are non-standard. We show that they are uniquely solvable in the corresponding Sobolev spaces and prove that their generalized resolvent decreases as $1/|\lambda|$ at infinity in $L_2(\mathbb{R}\times (0,1))$ and $W_2^1(\mathbb{R}\times (0,1))$.
