let φ be a w  -continuous homomorphism from a dual banach algebra to c. the notion of φ-connes amenability is studied and some characterizations is given. a type of diagonal for dual banach algebras is dened. it is proved that the existence of such a diagonal is equivalent to φ-connes amenability. it is also shown that φ-connes amenability is equivalent to so-called φ-splitting of a certain s...

limit to the tension reinforcement ratio ( ρ) in flexural high strength reinforced concrete (hsrc) members is based on the requirement that tension failure as sufficient rotation capacity are ensured at ultimate limit state. however, the provisions for the total amount of longitudinal reinforcement ratio ( ρ and ρ’) are not associated with any rational derivation. in this paper, a quantitative ...

Systems of linear diierential equations with constant coeecients, as well as Lotka{Volterra equations, with delays in the oo{diagonal terms are considered. Such systems are shown to be asymptotically stable for any choice of delays if and only if the matrix has a negative weakly dominant diagonal.

We study how the geometry of a projective variety X is reflected in the positivity properties of the diagonal ∆X considered as a cycle on X ×X. We analyze when the diagonal is big, when it is nef, and when it is rigid. In each case, we give several implications for the geometric properties of X. For example, when the cohomology class of ∆X is big, we prove that the Hodge groups H(X) vanish for ...

Kazuhisa Amemiya and Hideo Suganuma Research Center for Nuclear Physics (RCNP), Osaka University Mihogaoka 10-1, Ibaraki, Osaka 567-0047, Japan E-mail: [email protected] We study the origin of the abelian dominance in the maximally abelian (MA) gauge for the long-distance physics in terms of the interaction range mediated by gluons. In the MA gauge, diagonal gluon components behave as ...

Effect of double exchange and diagonal disorder on the magnetic and transport properties of La 1−x Sr x MnO 3. Abstract We use a model previously formulated based on the double exchange mechanism and diagonal disorder to calculate magnetization and conductivity for La 1−x Sr x MnO 3 type crystals as a function of temperature. The model represents each Mn 4+ ion by a spin S=1/2, on which an elec...
