In this paper, we ¯rst show that the pull-back mor- phism between two K-groups of the Steinberg varieties, obtained respectively from partial °ag varieties and quiver varieties of type A, is a ring homomorphism with respect to the convolution prod-uct. Then, we prove that this ring homomorphism yields a property of compatibility between two certain convolution actions.
