About Me

I have recently finished my PhD in pure mathematics and am currently looking for positions.

My research interests are in mathematical physics and modern geometry. This is probably closer to mathematics than physics.

Papers on the ArXiv.
"In physics you don't have to go around making trouble for yourself - nature does it for you" Frank Wilczek.

    Missed you Andrew. How is your wife? She is better than you no wander, just obvious as she can look into your deep eyes.
    Don't kill ladies with innocence, but with the reason of innocence. I killed a cat before. :)~~~~~
    Just kidding man. She gonna be okay, after God's Will.
    You seem gettng higher in field, professor. Keep on and leave if IT REALLY GOT PR...

    I do not know very much. I often surprise myself with my ignorance. But this is a good state of mind to be in.

    Dear friend, I hope again you took a look on my paper. http://spaceandconsensus.wordpress.com
    Presently discussing on thread "matter occupy space" in main forum and "space and consensus" in speculation.
    Previously I had left "universe smallest existence is neutral existence" and my hypothesis is it is "neutron" Till I have left one thing.

    Andrew ..... admire. You are a magnificent physicist/mathematician.

    I quite like Nakahara's book, thought it is not the most complete book mathematically speaking. It does however introduce you to many of the basic ideas of topology and geometry.
    Isham's Modern di®erential geometry for physicists is also quite good, but again lacks some rigour. Tohru Eguchi, Peter B. Gilkey, and Andrew J. Hanson. Phys. Rept.,66 is also good.

    Can you recommend any good introductory books on differentiable geometry? Preferably one with a lot of hand-holding, and in-depth explanations of the various concepts?

    In physics differential geometry probably is advanced mathematics used "day to day". The reason for this is that physics, or for sure classical physics is usually smooth, i.e. you can take derivatives and does not depend on exactly how you decide to present it. Both these are fundamental ideas in differential geometry.

    It seems to me that most advanced math is a form of, or heavily relies upon, differentiable geometry. Is this the case, or am I mistaken?

    Odd variables appear in quantum field theory when looking for semi-classical descriptions of fermions, like the electron and also are needed in gauge theories like Yang-Mills. Supersymmetric theories uses them, including superstring theory. They also can be very useful linear algebra and differential geometry as a neat description of alternating forms.
    So, Ok maybe I could include ...

    How about an entry on application of odd variables? Why would we use them other than for pure mathematical enjoyment?
