Generalized (co)integrals on coideal subalgebras
Paweł Kasprzak
Given a a Hopf algebra , its left coideal subalgebra and a non-zero multiplicative functional on , we define the space of left -integrals . We obse…
Integrals in left coideal subalgebras and group-like projections
Alexandru Chirvasitu, Pawel Kasprzak, Piotr Szulim
We develop a theory of right group-like projections in Hopf algebras linking them with the theory of left coideal subalgebras with two sided counital integrals. Every right group-l…
Shifts of group-like projections and contractive idempotent functionals for locally compact quantum groups
Paweł Kasprzak
A one to one correspondence between shifts of group-like projections on a locally compact quantum group which are preserved by the scaling group and contractive idem…
The Lattice of Idempotent States on a Locally Compact Quantum Group
Paweł Kasprzak, Piotr M. Sołtan
We study lattice operations on the set of idempotent states on a locally compact quantum group corresponding to the operations of intersection of compact subgroups and forming the…
