LetGbe either a compact group or a discrete group, letXbe its character group, and letG′be the character group ofX; then there is an isomorphism ofGontoG′so that the groupsGandG′may be identified.

Chapters discuss duality, linear mappings, matrices, determinant and trace, spectral theory, Euclidean structure, calculus of vector- and matrix-valued functions, matrix inequalities, kinematics and dynamics, convexity, the duality theorem, normed liner spaces, linear mappings between normed linear spaces, positive matrices, and solutions of systems of linear equations.
]From the paper [4], we have the duality theorem which says that the Laplace transform is a topological isomorphism from [F'.
The graduate textbook illustrates how Cohen-Macaulay rings arise naturally, develops the Hartshorne-Lichtenbaum vanishing theorem, applies two classes of rings to polyhedral geometry, explains Grothendieck's duality theorem, and defines D-modules over rings of differential operators.
