Modules



  • Example of projective module.

    • We consider a beautiful and very simple example of projective module $P$ such that it is not free and $P+P$ is one dimensional free module... (around 2001...)

  • Cohomological approach to determinant and berezinian

    • Do these exercises and you understand what is it determinant and Berezinian from cohomological point of view... (around 2005...)
