Hi everyone! I am new on this RTRfans group. I recently acquired a
copy -fresh one spanish version- of Sir Roger Penrose's book TRTR. What
can I say? I have been always loved to read scientific divulgation
books -a la Hawking, Stewart, Weinberg and so on-. Penrose book is
unique and without comparisson. The reason is all the mathematical
background in it. I am looking for some list of resources or something.
My academic background is Production Engineering. I have completed
Calculus (single and multivariable), Linear Algebra, Differential
Equation and Numerical Methods. There is so much math topics on
Penrose's book that is beyond my knowledge. I wish I could say I am
able to understand Topology, Calculus on Manifolds or Complex Analysis.
I'm sorry I am not able. That is the reason of this message. I'm hoping
someone out there can throw me a list of resources. I am willing to
learn new things and I would like to receive some help!

Thanks for reading
