In differential geometry, Kawasaki's Riemann–Roch formula, introduced by Tetsuro Kawasaki, is the Riemann–Roch formula for orbifolds.
It can compute the Euler characteristic of an orbifold.
Kawasaki's original proof made a use of the equivariant index theorem.
Today, the formula is known to follow from the Riemann–Roch formula for quotient stacks.
