In some of my past posts, I have mentioned “hyperbolic curvature“,”hyperbolic trigonometry” and “hyperbolic ideal points“. In this post I will share some artworks, based on hyperbolic geometry, by contemporary artists (from Tumblr): 200 more words

**— GRAPHS OF LARGE GIRTH —**

To refresh on a bit of graph theory, we define a *k*-regular graph to be a graph in which every vertex has… 1,495 more words

#### Understanding Geometry - 1

When we think about mathematics, what comes to our mind are the numbers and figures. The study of numbers is called arithmetic and the study of figures is called geometry (in very crude sense!). 513 more words

#### A Solution to High-Energy Quantum Gravity: AdS/CFT + Quantum Error Correcting Code = ???!

I went to a talk given by Daniel Harlow at Stanford last Thursday (2016 Oct) on Emergent Locality and Gravity & Quantum Error Correction. He started from summarizing the existing attempts to solve the short distance quantum gravity problem including string theory and the attempt to quantize the metric as a local field. 147 more words
