On the central coefficients of Bell matrices
Journal of integer sequences, Tome 14 (2011) no. 4
We use the Lagrange inversion theorem to characterize the central coefficients of matrices in the Bell subgroup of the Riordan group of matrices. We give examples of how by using different means of calculating these coefficients we can deduce the generating functions of interesting sequences.
