%0 Journal Article %T Paraconsistent second order arithmetic Z^#_2 based on the paraconsistent logic LP^# with infinite hierarchy levels of contradiction. Berry's and Richard's inconsistent numbers within Z^#_2 %A Jaykov Foukzon %J Mathematics %D 2009 %I arXiv %X In this paper paraconsistent second order arithmetic Z#2 with unrestricted comprehension scheme is proposed. We outline the development of certain portions of paraconsistent mathematics within paraconsistent second order arithmetic Z#2.In particular we defined infinite hierarchy Berry's and Richard's inconsistent numbers as elements of the paraconsistent field R^#. %U http://arxiv.org/abs/0906.3479v4
