We develop a calculus structure in the Banach lattice introduced in a preceding paper, having in mind an approximation problem appearing in non-smooth optimization. We show that the essential results depend as much on the order structure as on the analytical one. 相似文献

A fully discrete scheme for a class of multidimensional degenerate parabolic equations is proposed. The discretization is given by $supoesup piecewise linear finite elements in space and backward differences in time (the smoothing procedure is avoided). Numerical integration is used; hence the proposed method is easy to implement. Optimal error estimates in energy norms are proved for the solutions. 相似文献

The effect of substitution of double bonds by epoxy groups in 1(10)E,4E-germacranolides is studied by molecular mechanics. The probabilities of forming conformers in the epoxy derivatives are determined. Barriers to possible conformational transitions are estimated 相似文献

We prove that the dimension of harmonic functions with finite Dirichlet integral is invariant under rough isometries between
Riemannian manifolds satisfying the local conditions, expounded below. This result directly generalizes those of Kanai, of
Grigor'yan, and of Holopainen. We also prove that the dimension of harmonic functions with finite Dirichlet integral is preserved
under rough isometries between a Riemannian manifold satisfying the same local conditions and a graph of bounded degree; and
between graphs of bounded degree. These results generalize those of Holopainen and Soardi, and of Soardi, respectively.

We generalize the disjunctive approach of Balas, Ceria, and Cornuéjols [2] and devevlop a branch-and-cut method for solving
0-1 convex programming problems. We show that cuts can be generated by solving a single convex program. We show how to construct
regions similar to those of Sherali and Adams [20] and Lovász and Schrijver [12] for the convex case. Finally, we give some
preliminary computational results for our method.

Transcendence of the modular invariant in finite characteristic
Abstract. Let J be the Fourier expansion at infinity of the modular invariant j associated to a Drinfeld module of rank 2 defined on the algebraic closure of and t an element of the completion of . Then at least one of the two elements t, J(t) is transcendental over .
