A Cousin Complex for the Quantum Projective Space
Kobi Kremnizer, David Ssevviiri
Grothendieck constructed a Cousin complex for abelian sheaves on an arbitrary topological space. In a special setting, its dual called the BGG resolution is applicable in represent…
Feynman graphs, rooted trees, and Ringel-Hall algebras
Kobi Kremnizer, Matthew Szczesny
We construct symmetric monoidal categories $\LRF, \FD$ of rooted forests and Feynman graphs. These categories closely resemble finitary abelian categories, and in particular, the n…
Proof of the De Concini-Kac-Procesi conjecture
Kobi Kremnizer
In this paper we prove a conjecture by De Concini, Kac and Procesi \cite{CP} (Corollary \ref{conj}): The dimension of any $M\in U_q-\mood^χ$ is divisible by $l^{codim_\mathcal{B}\m…
Quantum flag varieties, equivariant quantum D-modules and localization of quantum groups
Erik Backelin, Kobi Kremnizer
Let $\Oq(G)$ be the algebra of quantized functions on an algebraic group and $\Oq(B)$ its quotient algebra corresponding to a Borel subgroup of . We define the category…
