本书是美国 数学家Peter Lax与康奈尔大学数学教授Maria Terrell合作的多元微积分教材,作为《微积分及其应用》（中译本见本丛书第32号）的续篇,其内容涵盖了平行于一元微积分的基础部分,包括：向量和矩阵、多元函数的连续性、多元函数的微分及其应用、多元函数的积分、向量值函数在曲线与曲面上的积分,以及作为一元函数微积分基本定理的多元推广——格林定理、散度定理、斯托克斯定理.此外,作者在散度定理、斯托克斯定理这一章还补充了对守恒律的介绍,并专辟一章介绍了数学物理中典型的几类偏微分方程.跟Lax的其他教材风格一致,作者在本书中一如既往地贯彻了牛顿的主张“达到理解的 方式是通过少量好的例子”.Lax对数学之应用造诣非凡,他成功地将来自物理的诸多例子融入这两本微积分教材,将数学与物理融会贯通.本书末尾提供了部分习题的答案.

The subject of this book is geometric integrators for differential equations with highly oscillatory solutions, including oscillation-preserving integrators, continuous-stage ERKN integrators, nonlinear stability and convergence analysis of ERKN integrators, functionally-fitted energy-preserving integrators, exponential collocation methods, volume-preserving exponential integrators, global error bounds of one-stage ERKN integrators for semilinear wave equations, linearly-fitted conservative/dissipative integrators, energy-preserving schemes for Klein–Gordon equations, Hermite–Birkhoff time integrators for Klein–Gordon equations, symplectic approximations for Klein–Gordon equations, continuous-stage modified leap-frog scheme for high-dimensional Hamiltonian wave equations, semi-analytical exponential RKN integrators,long-time momentum and actions behaviour of energy-preserving methods.The new geometric integrators are applied to problems with highly oscillatory solutions from sciences and engineering.
