Extended Affine Root Systems of Type BCSaeid Azam, Valiollah Khalili, and Malihe YousofzadehSaeid AzamDepartment of Mathematics University of Isfahan, Isfahan Iran, P.O.Box 81745 azam@math.ui.ac.ir, \smallskip Malihe Yousofzadeh Institute for Studies in Theoretical Physics and Mathematics (IPM) ma.yousofzadeh@math.ui.ac.ir, and Valiollah Khalili Department of Mathematics University of Isfahan, Isfahan Iran, P.O.Box 81745 v-k@math.ui.ac.ir Abstract: We classify the $BC$-type extended affine root systems for nullity $\leq 3$, in its most general sense. We show that these abstractly defined root systems are the root systems of a class of Lie algebras which are axiomatically defined and are closely related to the class of extended affine Lie algebras.
