To address these issues, two different approaches have been adopted: a detailed study of the stellar populations of S0s in the Fornax Cluster and a study of the Tully-Fisher Relation (TFR) of local S0s in different environments.Ph.D. Thesis submitted to The University of Nottingham, U.K. Please download the complete version at http://www.nottingham.ac.uk/~ppxapgg/phdthesis.pdfAstrophysicstext
