We present ac susceptibility measurements performed on (K, Ba)BiO<Subscript>3</Subscript>single crystals with different geometries: thick films, bars and hollow cylinders. We show that the h <Subscript>ac</Subscript> dependence of the real (χ′) and imaginary (χ′) parts of the ac susceptibility is in very good agreement with Brandt’s...</subscript></subscript>

Generalizing recent work of P. C. Matthews and A. L. Rukhin (Ann. Appl. Probab.3(1993), 454-466), we obtain the limit law of the largest interpoint Euclidean distance for a spherically symmetric multivariate sample of the Kotz distribution. While going through the proof, some errors in the...
