Operator Algebras and Identities,ie algebra of the generators of rotations (the angular momentum algebra) that has already been encountered in Chap. 11, Sect. .. We have also touched upon Lie algebras briefly in Chap. 12, Sect. .. In this chapter, I begin with a discussion of the basic algebra satisfied by the ladder operators . an

Orthogonal Polynomials,pic in mathematics and has been the subject of investigation for centuries now. Many of these special functions were first introduced into mathematics as solutions of specific second-order differential equations. Second-order ordinary differential equations comprise one of the important topics that

A Bit of Electromagnetism and Special Relativity,classical physics, namely, electromagnetism. I shall assume that you are already familiar with the elements of this subject. Its physical aspects will, therefore, be mentioned only very cursorily. The emphasis here will be on seeing how vector calculus provides a natural language for the description of . (EM fields, for short).
