dedicated to professor rüdiger göbel on his 60th birthday Let R be a ring and let simp-R be a representative set of all simple (right R-) modules. Denote by <ω the class of all modules which are finitely generated and have finite projective dimension. The little finitistic dimension of R is defined

✦ Synopsis
In this note we prove that for a left artinian ring of infinite global dimension there exists an indecomposable left module with both infinite projective dimension and infinite injective dimension. 2002 Elsevier Science (USA)
The purpose of this note is to prove the following theorem motivated by some results from [HRS].

We first define the notion of good filtration dimension and Weyl filtration dimension in a quasi-hereditary algebra. We calculate these dimensions explicitly for all irreducible modules in SL and SL . We use these to show that the global 2 3 dimension of a Schur algebra for GL and GL is twice the go
The existence and estimate of the upper bound of the Hausdorff dimension of the global attractor for the strongly damped nonlinear wave equation with the Dirichlet boundary condition are considered by introducing a new norm in the phase space. The gained Hausdorff dimension decreases as the damping
