Abstract
- In this letter we study the effects of a noncommutative minisuperspace, including matter degrees of freedom on a FRW universe with cosmological constant. In this setting the vacuum energy density can be calculated to be of the same order as the observed energy density of the universe.<br />Comment: 4 pages, RevTex 4
