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 of moment graphs...We prove an analogue of
the Riemann-Roch theorem for moment graphs. As an application, we obtain the
Riemann-Roch type theorem for equivariant $K$-theory of some Kac-Moody flag
varieties.(read more)
