Ricci Curvature, Yang-Mills curvature, New letter from Dr. Yau on Stable regular solution of Einstein-Yang-Mills equation

Hi Readers,

Its 3 AM in Mumbai.. I have been writing about Ricci Curvature, Yang Mills Curvature for a while. 

Some of you might like the new letter by Dr. Yau on it with Yang-Mills curvature tensor, coordinate transformation, etc. -

This is a very simple yet a genius letter. More to come on this topic. 

------------------------------

Different topic - 

I have been asked what books to read on Ricci Flow - 

The Book I recommend is Sobolev Inequalities, Heat Kernels under Ricci Flow, Poincare Conjecture by Qi S Zhang. 

Something which you might like in this book apart from my old lectures -
