Web11.1 Jacobians of Linear Matrix Transformations 413 c then taking the wedge product of differentials we have dY k =cp+1dX.Similarly, for example, if the elementary matrix E k−1 is formed by adding the i-th row of an identity matrix to its j-th row then the determinant remains the same as 1 and hence dY k−1 =dY k. In vector calculus, the Jacobian matrix of a vector-valued function of several variables is the matrix of all its first-order partial derivatives. When this matrix is square, that is, when the function takes the same number of variables as input as the number of vector components of its output, its determinant is referred to as the Jacobian determinant. Both the matrix and (if applicable) the determinant are often referred to simply as the Jacobian in literature. build body typeWebApr 14, 2024 · In order to improve the regulatory efficiency of the government in the construction process of the green financial system, the multi-stage dynamic evolution game model of green financial system from the perspective of bilateral moral risk is constructed and analyzed.
