I recently organised a GIAN program (brochure) on the relation between the theorey of Minors and that of Homomorphisms of graphs.
The main speaker is Reza Naserasr, IRIF, France.

**An article on an upcoming organic farming technique. It is only being written and is incomplete as of now. I hope to finalise it in a couple of manths. You can access the first draft version Here**
