PROOF: Let {wt , bt}∞t=0 denote the set of contracts in the optimal hybrid equilibrium, and let et denote the effort implemented at t (note that {wt , bt} is offered and accepted provided that the principal has not defaulted at any τ < t). Obviously, u0 = ū 1−δ must hold, otherwise w0 can be reduced by a small amount and make both types better off. Next, suppose towards a contradiction that ut+...

We study the well-posedness of Cauchy problem for the fourth order nonlinear Schrödinger equations i∂t u=−ε u+ 2u+ P (( ∂ x u ) |α| 2, ( ∂ x ū ) |α| 2 ) , t ∈R, x ∈Rn, where ε ∈ {−1,0,1}, n 2 denotes the spatial dimension and P(·) is a polynomial excluding constant and linear terms. © 2006 Elsevier Inc.

Abstract This paper analyzes and supports the claim that Vedic Sanskrit preserves traces of contrast between Indo-European labiovelars plain velars—a striking archaism in Indo-Iranian family, which otherwise collapsed two velar series. These labiovelar vestiges emerge because pervasive labialization syllabic consonantal rhotics at all attested stages family. Two rhotic environments are examined...

We give some conditions that ensure the validity of a Comparison principle for the minimizers of integral functionals, without assuming the validity of the Euler–Lagrange equation. We deduce a weak maximum principle for (possibly) degenerate elliptic equations and, together with a generalization of the bounded slope condition, the Lipschitz continuity of minimizers. To prove the main theorem we...

The report presents the development of the time-boundary element methodology and a description of the related software based on a stepped method of numerical inversion of the integral Laplace transform in combination with a family of Runge-Kutta methods for analyzing 3-D mixed initial boundary-value problems of the dynamics of inhomogeneous elastic and poro-elastic bodies. The results of the nu...

Let ẽ ≥ φ be arbitrary. A central problem in arithmetic Lie theory is the computation of symmetric arrows. We show that ū ≡ ∞. In contrast, this reduces the results of [33] to an approximation argument. Therefore it is essential to consider that may be smooth.

I review recent progress in understanding the structure of the nucleon sea and the role of the nucleon’s pion cloud. In particular, I discuss the consequences of the pion cloud for the d̄ − ū asymmetry in the proton, the neutron’s electric form factor, and the proton’s electric to magnetic form factor ratio.
