"Higher-Order Finite Element Methods" by Pavel Solin, Karel Segeth, and Ivo Dolezel

Page 175: relation (3.61) only holds in 2D. To be valid in 3D, its right-hand side must be multiplied from left by the Jacobi matrix of the reference map, \frac{\mbox{D}\bfx_K}{\mbox{D}\bfxi}.
Page 176: There should be no transposition in relation (3.64).
Page 190: On the left-hand side of relation (3.92) should be index 'ji' instead of 'ij'.
