DNS, A few points to keep in mind
A few points about what DNS can do and what it cannot do. DNS is simply a database that provides answers to questions. It provides no geographical information and it is not the same as IP routing.

Giovanni Cerulli-Irelli : Quiver Grassmannians of Dynkin type
Abstract: Given a finite-dimensional representation M of a Dynkin quiver Q (which is the orientation of a simply-laced Dynkin diagram) we attach to it the variety of its subrepresentations. This variety is strati ed according to the possible dimension vectors of the subresentations of M. E

Philip Boalch - Nonabelian Hodge spaces and nonlinear representation theory
Abstract: The theory of connections on curves and Hitchin systems is something like a “global theory of Lie groups”, where one works over a Riemann surface rather than just at a point. We’ll describe how one can take this analogy a few steps further by attempting to make precise the class

The Graceful Tree Conjecture | Famous Math Problems 4 | NJ Wildberger
The Graceful Tree Conjecture, or Ringel-Kotzig conjecture, concerns certain labellings of the vertices of a graph G introduced by A. Rosa in 1967. We introduce some basic terminology of graph theory, give examples of graceful and non-graceful graphs, and discuss evidence for the conjecture
