Abstract

In this paper, we introduce the almost linear spaces, a generalization of linear spaces. We prove that if the almost linear space X has a finite basis then, as in the case of a linear space, the cardinality of bases for the almost linear space X is unique. In the case X = Wx ＋ Vx, we prove that B'= {<TEX>$\chi$</TEX>'<TEX>$_1,...,x'_n</TEX>} is a basis for the algebraic dual X<TEX>$^#$</TEX> of X if B = {<TEX>$\chi$</TEX>'<TEX>$_1,...,x'_n</TEX>} is a basis for the almost linear space X. And we have an example X(<TEX>$\neq$</TEX>Wx ＋ Vx) which has no such a basis.
