 equation
 For these polynomials we prove an integral representation, a combinatorial formula, Pieri rules, Cauchy identity, and we also show that they do not satisfy any rationalq-difference equation. The Yang-Baxter equation admits two classes of elliptic solutions, the vertex type and the face type. The inverse conductivity problem to the the elliptic equation ${\rm div}((1+(k-1)\chi_D)\nabla u)=0\ {\rm in }\ \Omega$ is considered. As applications, the wave equation on?+ × ?+ and the heat equation in a semi-infinite rod are considered in detail. Pointwise fourier inversion: A wave equation approach 更多
 equations
 The list consists of many series defined by simple equations, and of several exceptional superalgebras, among themE(3, 6). We study boundary value problems for the time-harmonic form of the Maxwell equations, as well as for other related systems of equations, on arbitrary Lipschitz domains in the three-dimensional Euclidean space. We study boundary value problems for the time-harmonic form of the Maxwell equations, as well as for other related systems of equations, on arbitrary Lipschitz domains in the three-dimensional Euclidean space. We study the existence and regularity of compactly supported solutions φ = (φv)v=0/r-1 of vector refinement equations. They are of particular importance in solving differential and integral equations. 更多
 space equations
 We present an exact solution of the Einstein empty-space equations referring to four particles in relative motion. A numerical solution of the state-space equations is applied in order to obtain a step response of the transformer winding. Recently an exact solution of Einstein's empty-space equations referring to four uniformly accelerated particles was given. One of the main results of the paper is to show what extra conditions are needed, in addition to those required for input-output-wise linearization, in order to achieve full linearity of both state-space equations and output map. This suggests a danger in the use of 'velocity space' equations to model the effects of evaporation. 更多
 In the technical designs of the supporting surfaces of machine elements 目前工程界计算机械零件工作表面,或者只考虑其弹性变形的影响,或者只计及润滑油层的作用。然而大多数零件表面的实际状态是,同时存在弹性变形和润滑油层,二者共同影响表面的应力分布和承载能力,而且相互影响,对于重载、大曲率差、低弹性模数的表面(如齿轮、蜗轮和轴承的表面)尤为突出。近年来一个新的理论——弹性流体力学润滑理论已经发展起来。本文介绍了同时计及弹性变形和流体动力学作用而建立起来的方程,收集和比较了几个已经发表的结果,附有若干实例说明该理论在实际工作中的意义,并讨论了今后的发展前景。 The natural frequencies, the equation of motion and the node of vibration are discussed for the vibration system of a cradle dynamic balancing machine.
