I am the father of a son who does not have access to the resources needed to accomplish his goals in mathematics. He is currently serving a prison term for a OWI causing death. He has turned his life around and has dedicated his life to studying mathematics. I am using this site for guidance and assistance in getting him the information he needs to be successful. Please understand I am a layman and I am just acting as a conduit for my son. His current area of interest is in scattering theory.
