... multiplicities of eigenvalues 0 and −1 of G. Observe that two vertices of G belong to the same cluster (or to the set of isolated vertices) exactly if the corresponding leaves of T have a common ... fixed vertex of M, • −1 in turn to exactly one other vertex of M, • 0 to all other vertices of G. Then the constructed vectors constitute a simply structured basis of Eig(−1; G)....

... hyperbolic. 3. Proof of the Theorem 2.8 for the Case n =2 Suppose that A T = A, i.e. a 12 = a 21 . We prove that the system (1.1) is hyper- bolic. On the Hyperbolicity of some Systems of Nonlinear ... have m ij =(−1) 1+i det M ij . Proof. From (2.15), m ij = n−1  k=1 ξ k ∂g i ∂W jk . (2.17) From (2.7) we get Vietnam Journal of Mathematics 34:1 (2006) 109–128 On the Hyperbolicity...

... inverse hook length of the diagram, i.e. the inverse product of the hook lengths of all its boxes. Finally, we denote by F (Y ) the set of diagrams obtained by adjonction of one box to Y according to ... numbers of FPL configurations pertaining to certain types of link patterns. Making use of the Razumov and Stroganov Ansatz, these conjectures are based on the analysis of the...

... for PAPR distri- bution of OFDM/TDM signal and then, we develop the expression for the capacity of OFDM/TDM using MMSE-FDE. A. PAPR of OFDM/TDM The baseband oversampled OFDM/TDM signal given by (2) ... PAPR problem of conventional OFDM at the cost of slight decrease in spect rum efficiency. The capacity of OFDM/ TDM using MMSE-FDE is o btained based on the Gaus- sian assumption o...
