Macodi-Ringia 1 Department of Mathematics, Mindanao State University, Marawi City, Philippines The noncentral Stirling numbers of the first and second kind are certain generalization of the classical Stirling numbers of both kinds. In this paper, a kind of generalized Bell numbers, called noncentral Bell numbers, are defined in terms of noncentral Stirling numbers of the second kind. Some properties parallel to the ordinary Bell numbers are established including the Hankel transform of noncentral Bell numbers. Moreover, an alternative proof for the Hankel transform of (r, )-Bell numbers is presented. http://pubs.sciepub.com/tjant/2/2/1/tjant-2-2-1.pdf Stirling numbers Bell numbers Whitney numbers Dowling numbers Catalan numbers binomial transform Hankel transform
