In this paper, we study sign patterns allowing nilpotence of index k and obtain four methods to construct sign patterns allowing nilpotence of index at most k, which generalizes some recent results. }, journal = {International Journal of Mathematical and Computational Sciences}, volume = {7}, number = {4}, year = {2013}, pages = {720 - 724}, ee = {https://publications.waset.org/pdf/9996944}, url = {https://publications.waset.org/vol/76}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 76, 2013}, }
