Popis: We study relationships between the restricted unrolled quantum group U ‾ q H ( sl 2 ) at q = e π i / r , and the singlet vertex operator algebra M ( r ) , r ≥ 2 . We use deformable families of modules to efficiently compute ( 1 , 1 ) -tangle invariants colored with projective U ‾ q H ( sl 2 ) -modules. These invariants relate to the colored Alexander tangle invariants studied in [6] , [40] . It follows that the regularized asymptotic dimensions of characters of M ( r ) , studied previously by the first two authors, coincide with the corresponding modified traces of open Hopf link invariants. We also discuss various categorical properties of M ( r ) -mod in connection to braided tensor categories.
