报告摘要:

This work is devoted to the $A$-sequence characterization of the Riordan arrays with type-I $B$-sequences and the $Z$-sequence characterization of the Riordan arrays with type-II $B$-sequences. The computation schemes of two type $B$-sequences based on the characterization are given. An application of $B$-sequences to the second structure RNA matrices is discussed. Some subgroups characterized by $A$-sequences are presented. Finally, we investigate the sequence characterization of centralizers of the Riordan group, reverse sets of Riordan arrays, pseudo Riordan involutions, and the Pascal like matrices.
