The book is divided into five sections: 1 The Business Model Canvas, a tool for describing, analyzing, and designing business models, 2 Business Model Patterns, based on concepts from leading business thinkers, 3 Techniques to help you design business models, 4 Re-interpreting strategy through the business model lens, and 5 A generic process to help you design innovative business models, tying together all the concepts, techniques, and tools in Business Model Generation. The last section offers an outlook on five business model topics for future exploration. Finally, the afterword provides a peek into “the making of” Business Model Generation

定义1如果两个矩阵A=[ai]和B=[b]的行数和列数分别相等,且各对应元素也相等,即a=b (i=1,2m;j=1,n),就称A和B相等,记作 A=B

命题如果n维空间V上的线性变换A的矩阵相似于对角矩阵,则A在任一不变子空 间M上(的限制)的矩阵相似于对角矩阵。 证明若V上的线性变换A的矩阵相似于对角矩阵,则V可以分解为特征子空间的直 和。记A的所有特征值为,2,2,则V=V4V,取M=nV, 断言M=M1M2⊕M,首先要证明

You work for an airline you have just received a letter from a customer who says that she had a terrible flight, that her bags did not arrive until two days later, and that one of her bags was broken. Write a letter apologizing and ask for further information so that you can arrange

4.2.4子空间的直和与直和的四个等价定义 定义设V是数域K上的线性空间,2…,是V的有限为子空间。若对于∑中任一向量,表达式a=a1+a2+…+am,a1e,i=12,m是唯一的,则称∑V为直和,记为

在极限lim[1+a(x)]a(x)中,只要a(x)是无穷小,就有 lim[+a(x) ](x)=e. 这是因为,令u=,则u→∞,于是
