Popis:	We give a lower bound for the numerical index of two-dimensional real spaces with absolute and symmetric norm. This allows us to compute the numerical index of the two-dimensional real $L_p$-space for $3/2\leq p\leq 3$. Comment: This article has been accepted for publication in Linear and Multilinear Algebra, published by Taylor & Francis
