Indeed, symmetries are a powerful and versatile approach for the<br>analysis of physical models in a fruitful interplay between various<br>areas of physics, (such as gauge fields, supergravity, particle physics,<br>statistical mechanics, condensed matter) and mathematics (algebraic<br>geometry, cohomology, topology, dynamical systems). Some examples I have<br>focused on are using techniques in noncommutative geometry for the<br>quantization of space-time in high-energy physics; mapping the geometry<br>of exceptional Lie groups to determine the global properties of the<br>group manifold (generalization of Euler angles) lattice gauge theories<br>and instantons in plasma physics; applications of a holographic map to<br>compute non-trivial topological properties of electrons in graphene like<br>2-dimensional materials in condensed matter physics from a gravity<br>theory in one dimension higher.</div></div>
