ACM Communications in Computer Algebra, Vol. 45, No. 3, Issue 177, September 2011 Simplicial blowups and discrete normal surfaces in simpcomp Felix E enberger and Jonathan Spreer Institut f r Geometrie und Topologie u Universit t Stuttgart, Germany a effenberger@mathematik.uni-stuttgart.de, spreer@mathematik.uni-stuttgart.de Abstract simpcomp is an extension to GAP, the well known system for computational discrete algebra. It allows the user to work with simplicial complexes. In the latest version, support for simplicial blowups and discrete normal surfaces was added. Furthermore, new functions for constructing certain in nite series of triangulations have been implemented and interfaces to other software packages have been improved to previous versions. Introduction simpcomp [8, 7] is a package for working with simplicial complexes. Its aim is to provide the user with a broad spectrum of functionality regarding simplicial constructions and the calculation of properties of simplicial complexes. Important goals during the development of simpcomp were interactivity, ease of use, completeness of documentation and ease of extensibility. The software allows the user to interactively construct simplicial complexes and to compute their properties in the GAP [9] or SAGE [14] shell. It is sought of as a tool for researchers to verify or disprove a
