Abstract
In this final chapter we introduce the spaces \(L_{p(\cdot)}\) with variable exponent p and establish their basic properties. When I is a bounded interval (a,b) in \(\mathbb{R}\) the Hardy operator \(T_a:L_P(.)(I)\longrightarrow L_{p(.)}(I)\) given by \(T_af(x)=\int_{a}^{x}f(t)dt\) is studied: the asymptotic behaviour of its approximation, Bernstein, Gelfand and Kolmogorov numbers is determined. To conclude, a version of the \({p(\cdot)}\)-Laplacian is presented and the existence established of a countable family of eigenfunctions and eigenvalues of the corresponding Dirichlet problem.
