Contractive idempotents on locally compact quantum groups
Matthias Neufang, Pekka Salmi, Adam Skalski +1
A general form of contractive idempotent functionals on coamenable locally compact quantum groups is obtained, generalising the result of Greenleaf on contractive measures on local…

Inclusions of ternary rings of operators and conditional expectations
Pekka Salmi, Adam Skalski
It is shown that if T is a ternary ring of operators (TRO), X is a nondegenerate sub-TRO of T and there exists a contractive idempotent surjective map P:T-->X, then P has a unique,…

Closed quantum subgroups of locally compact quantum groups
Matthew Daws, Paweł Kasprzak, Adam Skalski +1
We investigate the fundamental concept of a closed quantum subgroup of a locally compact quantum group. Two definitions - one due to S.Vaes and one due to S.L.Woronowicz - are anal…
