Sweeping on Dirac Fields

Intended to follow what has been posted of late (https://foxtrotpaparomeo.wordpress.com/2016/01/28/2015-ft-highlights/) in the subject of quantum field theory prior to leaving this subject temporarily as I will proceed with my summer physics course in blackholes and gr this 2016. In this document, which is still unfinished and still being drafted in the process, I am attempting to wrap up sweepingly on Dirac fields although only dealing with the Lagrangians and Actions and mainly based on my self-worked out exercises dealing on the said topics. Updated versions of this document will follow in coming posts.

Something wrong in slideshare, so here is a wordpress link of the document https://foxtrotpaparomeo.files.wordpress.com/2016/03/sweeping_discussion_on_dirac_fields.pdf
