Abstract: | The present Part II continues the discussion in Part I of the Drazin inverse as applied to the Hill system. A second type of Drazin inverse key-matrix (V-key) is treated in detail. The V-key is of a more complex nature than the W-key considered in Part I and allows for the use of a general involution. There are several worked out Examples and some Problems for the reader. The reader should have available Part I which includes a mod 26 multiplication table. |
