Abstract

The objective of this article is to present an original proof of the following theorem: There is a generic extension of the Solovay's model $L (\mathbb{R})$ where there is a linear order of $P(\mathbb{N})/fin$ that extends to the partial order $(P(\mathbb{N})/fin),\leq^{\star})$. Linear orders of $P(\mathbb{N})/fin$ are important because, among other reasons, they allow constructing non-measurable sets.
