Corcino rcorcino@yahoo.com 2 Mathematics Department, Cebu Normal University, Cebu City, Philippines 6000 Research Institute for Computational Mathematics and Physics, Cebu Normal University, Cebu City, Philippines 6000 Some combinatorial properties of -Stirling numbers are proved. Moreover, two asymptotic formulas for -Stirling numbers of the first kind derived using different methods are discussed and corresponding asymptotic formulas for the -Stirling type numbers of the first kind are obtained as corollaries. http://pubs.sciepub.com/tjant/7/3/2/tjant-7-3-2.pdf asymptotic analysis asymptotic formula Stirling numbers generalized Stirling numbers
