Correspondence theorems for Hopf algebroids with applications to affine groupoids
L El Kaoutit, A Ghobadi, P Saracco… - Canadian Journal of …, 2024 - cambridge.org
We provide a correspondence between one-sided coideal subrings and one-sided ideal two-
sided coideals in an arbitrary bialgebroid. We prove that, under some expected additional …
