K theory

[′kā ‚thē·ə·rē]
(mathematics)
The study of the mathematical structure resulting from associating an abelian group K (X) with every compact topological space X in a geometrically natural way, with the aid of complex vector bundles over X. Also known as topological K theory.

In [12] and [14], Lascoux and Schutzenberger introduced (double) Grothendieck polynomials indexed by permutations as representatives of K-theory classes of structure sheaves of Schubert varieties in a full flag variety.
The first, developed mainly by Bloch, Kato, and Tsuji, uses algebraic K-theory, syntomic complexes, and p-adic vanishing cycles, while the second, more in line with Tate~s original ideas, was developed by Faltings using his almost mathematics and purity theorems.

But Nicusor Dan, a mathematician who graduated from the Sorbonne University in Paris, decided to fight back - even if this meant spending less time on his cherished research about polylogarithms and the K-theory at the Romanian Institute for Mathematics.
Among the topics are the functoriality of Rieffel's generalized fixed-point algebras for proper actions, division algebras and supersymmetry, Riemann-Roch and index formulae in twisted K-theory, noncommutative Yang-Mills theory for quantum Heisenberg manifolds, distances between matrix algebras that converge to coadjoint orbits, and geometric and topological structures related to M-branes.
