On -conservative and boundedly -conservative four-dimensional matrices

Recently, Mursaleen and Mohiuddine [M. Mursaleen, S.A. Mohiuddine, Regularly - conservative and -coercive four-dimensional matrices, Comput. Math. Appl. 56 (2008) 1580 1586] defined and characterized the regularly -conservative four-dimensional matrices by using the concept of regular convergence (r-convergence) of double sequences x D .xjk/. In this paper, we characterize four-dimensional -conservative and boundedly -conservative matrices corresponding to the concept of p-convergence and boundedly p-convergence of double sequences, respectively.
