Description
Internal Collaboration. With Graham Ellis and Tuan Anh Bui (both National University of Ireland at Galway) , I incorporate cell complexes into HAP, the Homological Algebra Programming package of GAP. An example of the results obtained with Ellis is included in my articleThe homological torsion of PSL_2 of the imaginary quadratic integers,Transactions of the AMS, volume 365 (2013), pp. 1603�1635.Based on these calculations, I have used the methods of my joint paperThe mod 2 cohomology rings of SL_2 of the imaginary quadratic integers, preprint joint with Ethan Berkove, to successfully obtain a cohomology ring which plays an important role in a projectof Gael Collinet (Universite de Strasbourg), which is being pursued by Tuan Anh Bui.| Period | 0001 |
