    Notes: Abstract A bi-infinite sequence ...,t −2,t −1,t 0,t 1,t 2,... of nonnegativep×p matrices defines a sequence of block Toeplitz matricesT n =(t ik ),n=1,2,...,, wheret ik =t k−i ,i,k=1,...,n. Under certain irreducibility assumptions, we show that the limit of the spectral radius ofT n , asn tends to infinity, is given by inf{σ(ξ)∶ξ∈[0,∞]}, where σ(ξ) is the spectral radius of Σ j∈z t j ξ j .

    Description / Table of Contents: Zusammenfassung Für dünne, elastische, in radialer Richtung gedrückte Kreisplatten aus isotropen oder orthotropen Schichten werden drehsymmetrische nichtlineare Beulgleichungen hergeleitet. Das lineare Eigenwertproblem wird für am Rand eingespannte oder frei aufliegende heterogene isotrope Kreisplatten in geschlossener Form gelöst. Invariante Beulparameter, die eine Optimierung ermöglichen, werden erhalten und einige numerische Beispiele angegeben.
    Notes: Summary Axisymmetric nonlinear buckling equations are introduced for thin elastic circular plates composed of isotropic or orthotropic layers, uniformly compressed in the radial direction. The linear eigenvalue problem is solved in closed form for heterogeneous isotropic circular plates with clamped or simply supported circumference. Invariant buckling parameters are obtained which enable optimization. Several numerical examples are shown.
