A Riemann-Roch type theorem for twisted fibrations of moment graphs
Martina Lanini, Kirill Zainoulline
In the present paper we extend the Riemann-Roch formalism to structure algebras of moment graphs. We introduce and study the Chern character and pushforwards for twisted fibrations…

Twisted quadratic foldings of root systems
Martina Lanini, Kirill Zainoulline
In the present paper we study twisted foldings of root systems which generalize usual involutive foldings corresponding to automorphisms of Dynkin diagrams. Our motivating example…
