✦ Synopsis

For their bijective proof of the hook-length formula for the number of standard tableaux of a fixed shape Novelli et al. define a modified jeu de taquin which transforms an arbitrary filling of the Ferrers diagram with 1, 2, . . . , n (tabloid) into a standard tableau. Their definition relies on a total order of the cells in the Ferrers diagram induced by a special standard tableau, however, this definition also makes sense for the total order induced by any other standard tableau. Given two standard tableaux P, Q of the same shape we show that the number of tabloids which result in P if we perform the modified jeu de taquin with respect to the total order induced by Q is equal to the number of tabloids which result in Q if we perform the modified jeu de taquin with respect to P. This symmetry theorem extends to skew shapes and shifted skew shapes.

In this work we provide local bifurcation results for equations involving the p-Laplacian in balls. We analyze the continua C n of radial solutions emanating from (l n, p , 0), {l n, p } being the radial eigenvalues of -D p . First, we show that the only nontrivial solutions close to (l n, p , 0) li

A new approach for gray-level image coding using binary morphological operations on the image bit-planes is presented. This approach is based on a Geometric Sampling Theorem (GST), and on a modified morphological skeleton. The theorem, which is proved in this paper, states conditions for the reconst
