I am Kridi Khelil.
I am researchstudent at the University of Tokyo. I joined this group because I didn't use mathmatics for years and I curently need help to solve some basic problems.
I hope you find your time here productive and enjoyable. We will be glad to help you, and if you find questions with which you can help, that would be wonderful, not only for the recipient, but it will make you a better student as well...there are few better ways to improve your skills than by helping others.
