In this paper we use the theory of variational inequalities to study the general economic equilibrium problem with production. The variational inequality is defined on a bounded set. Existence, uniqueness and sensitivity of the equilibrium point (pair of price vector and activity vector) are discussed through studying this variational inequality. 相似文献

We present Monte Carlo simulations of the formation of (1×2) islands in the case of the 2

AB reaction occurring via the Langmuir-Hinshelwood mechanism on a square lattice under steady-state conditions. The model employed takes into account
the effect of anisotropic lateral B-B interactions on the rates of B diffusion and elementary reaction events. The results obtained with qualitatively realistic ratio of the rate of elementary
reaction steps indicate that the average island size depends on the details of diffusion and reaction dynamics in a similar
way as in the earlier studied case of the simplest A

B reaction running via the Eley-Rideal mechanism.

A variational technique to deal with nonlinear dissipative pulse propagation is established. By means of a generalization
of the Kantorovitch method, suitable for non-conservative systems, we are able to cope with an extended nonlinear Schr?dinger
equation (NLSE) which describes pulse propagation under the influence of nonlinear loss and/or gain, in particular, in the
presence of two-photon absorption (TPA). Based on the characteristics of the exact solution of the NLSE in the absence of
TPA, we investigate the effects of frequency dispersion of the nonlinear susceptibility associated to the two-photon resonance,
obtaining the necessary conditions for a solitary wave solution, even in the presence of a self-steepening term.

This paper presents a generalization of Rao's covariance structure. In a general linear regression model, we classify the error covariance structure into several categories and investigate the efficiency of the ordinary least squares estimator (OLSE) relative to the Gauss–Markov estimator (GME). The classification criterion considered here is the rank of the covariance matrix of the difference between the OLSE and the GME. Hence our classification includes Rao's covariance structure. The results are applied to models with special structures: a general multivariate analysis of variance model, a seemingly unrelated regression model, and a serial correlation model. 相似文献

Conjugation coactions of the quantum general linear group on the algebra of quantum matrices have been introduced in an earlier paper and the coinvariants have been determined. In this paper the notion of orbit is considered via co-orbit maps associated with
-points of the space of quantum matrices, mapping the coordinate ring of quantum matrices into the coordinate ring of the quantum general linear group. The co-orbit maps are calculated explicitly for 2×2 quantum matrices. For quantum matrices of arbitrary size, it is shown that when the deformation parameter is transcendental over the base field, then the kernel of the co-orbit map associated with a
-point ξ is a right ideal generated by coinvariants, provided that the classical adjoint orbit of ξ is maximal. If ξ is diagonal with pairwise different eigenvalues, then the image of the co-orbit map coincides with the subalgebra of coinvariants with respect to the left coaction of the diagonal quantum subgroup of the quantum general linear group. 相似文献

is one of the applications of (Ⅰ), in which the angular stiffness, the lateral stiffness and the corresponding stress distributions of Omega-shaped bellows were calculated, and the present results were compared with those of the other theories and experiments. It is shown that the non-homogeneous solution of (Ⅰ) can solve the pure bending problem of the bellows by itself, and be more effective than by the theory of slender ring shells; but if a lateral slide of the bellows support exists the non-homogeneous solution will no longer entirely satisfy the boundary conditions of the problem, in this case the homogeneous solution of (Ⅰ) should be included, that is to say, the full solution of (Ⅰ) can meet all the requirements. 相似文献
