This is the official page for the computer algebra system ApCoCoA.

ApCoCoA stands for Applied Computations in Computer Algebra. It is based on the computer algebra system CoCoA, which can be found at Some information can also be found in the CoCoA section of this wiki. There is absolutely NO link to the Apple cocoa interface!

ApCoCoA is developed by the ApCoCoA Team, which is lead by Martin Kreuzer, and is always looking for new contributors.


The software ApCoCoA is a client/server application. The functionality of the server is implemented in ApCoCoALib, a GPL'ed C++ library. The client consists of an interpreter/a parser and an open source graphical user interface. All the functionality of CoCoA is provided by this client and in addition there are some new commands available. These additional commands are described in the ApCoCoA Manual.
