The story began quite accidentally. In 1977, at the University of Namur (Belgium) Professor JosephDelhalle asked the PhD student Christian Demanet to perform a numerical test. The test consisted oftaking a simple infinite polymer (the infinite chain LiH LiH LiH had been chosen), to use thesimp[r]

22CHAPTER 2LINEAR ALGEBRAVector and matrix concepts have proved indispensable in the development ofthe subject of dynamics. The formulation of the equations of motion using theNewtonian or Lagrangian approach leads to a set of second-order simultaneousdifferential equations. For convenience,[r]
• If a row (column) is a linear combination of other rows (columns), then detA =0. In particular, if two rows (columns) are identical then detA =0. Conclusion:in a Slater determinant the spinorbitals have to be linearly independent, other-wise the Slater determinant is equal zero.• If in a matrix[r]
