我们研究了与Poincaré代数的κ-变形相关的经典r-矩阵引起的具有变形4D Minkowski时空的Yang-Baxter sigma模型。 这些经典的κ-Poincarér-矩阵描述了三种变形：1）标准变形，2）速动变形，和3）视锥变形。 对于每个变形，从关联的r-矩阵计算度量和二维B场。 与修改后的经典Yang-Baxter方程有关的前两个变形分别导致dS 4和AdS 4的T对偶。 第三次变形与均一的经典Yang-Baxter方程相关，导致了随时间变化的pp波背景。 最后，我们为广义κ-Poincarér-矩阵构造一个Lax对，该矩阵统一了上述三种特殊情况下的变形。

Linear Algebra and Its Applications, Second Edition presents linear algebra as the theory and practice of linear spaces and linear maps with a unique focus on the analytical aspects as well as the numerous applications of the subject. In addition to thorough coverage of linear equations, matrices, vector spaces, game theory, and numerical analysis, the Second Edition features student-friendly additions that enhance the book's accessibility, including expanded topical coverage in the early chapters, additional exercises, and solutions to selected problems. Beginning chapters are devoted to the abstract structure of finite dimensional vector spaces, and subsequent chapters address convexity and the duality theorem as well as describe the basics of normed linear spaces and linear maps between normed spaces. Further updates and revisions have been included to reflect the most up-to-date coverage of the topic, including: The QR algorithm for finding the eigenvalues of a self-adjoint matrix The Householder algorithm for turning self-adjoint matrices into tridiagonal form The compactness of the unit ball as a criterion of finite dimensionality of a normed linear spaceAdditionally, eight new appendices have been added and cover topics such as: the Fast Fourier Transform; the spectral radius theorem; the Lorentz group; the compactness criterion for finite dimensionality; the characterization of commentators; proof of Liapunov's stability criterion; the construction of the Jordan Canonical form of matrices; and Carl Pearcy's elegant proof of Halmos' conjecture about the numerical range of matrices. Clear, concise, and superbly organized, Linear Algebra and Its Applications, Second Edition serves as an excellent text for advanced undergraduate- and graduate-level courses in linear algebra. Its comprehensive treatment of the subject also makes it an ideal reference or self-study for industry professionals.
