%0 Journal Article %T The Hausdorff Dimension of the Penrose Universe %A L. Marek-Crnjac %J Physics Research International %D 2011 %I Hindawi Publishing Corporation %R 10.1155/2011/874302 %X Penrose fractal tiling is one of the simplest generic examples for a noncommutative space. In the present work, we determine the Hausdorff dimension corresponding to a four-dimensional analogue of the so-calledPenrose Universe and show how it could be used in resolving various fundamental problems in high energy physics and cosmology. %U http://www.hindawi.com/journals/phys/2011/874302/
