I will discuss the Killing operator ($K_{ab}[v] = \nabla_a v_b + \nabla_b v_a$) as an overdetermined differential operator and its (formal) compatibility complex. Basic familiarity with point-set (general) topology: metric spaces, topological spaces, separation axioms, compactness, completeness.

The ( ): ( 1.. h. (1/ 2.8.. 1/ 2). c.. .1. The aim of the project is to investigate the interaction between higher algebraic structures on the one hand, and questions arising from geometry and topology on the other hand. To establish uniqueness of best rank one approximation, in particular for partially symmetric tensors, one needs to use some soft analysis and...

I mean, on the right we have a square, and the Hévéa Torus is… well, a weird twisted shape! From the 1980's, Grothendieck's "Esquisse d'un Programme" triggered tremendous developments in number theory and arithmetic geometry, extending from the studies of anabelian geometry and related Galois representations to those of polylogarithms and multiple zeta values, motives, rational points on arithmetic varieties, and effectiveness questions in arithmetic geometry.

However, mathematically rigorous theories to support the simulation results and to explain their limiting behavior are still in their infancy. Explain why we say that V( − 1) will intersect V( ) in one point at infinity with multiplicity two. and ℎ( ) = 2 − 1 have zero. Changing the shape of the polygon induces an SL(2,R)-action on the moduli space of abelian differentials, called the Teichmüller dynamics. We look at how many points a straight line will...
