# Java algebra system, Jython access to Signature based Gröber base Python scripts.

The Java Algebra System (JAS) is an object oriented, type safe and multi-threaded approach to computer algebra. JAS provides a well designed software library using generic types for algebraic computations implemented in the Java programming language using the JVM runtime infrastructure. The library can be used as any other Java software package or it can be used interactively or interpreted through an jython (Java Python) or jruby (Java Ruby) front ends. The focus of JAS is at the moment on commutative, solvable and non-commuative polynomials, power series, Groebner bases, factorization, real and complex roots and applications. By the use of Java as implementation language JAS is 64-bit and multi-core cpu ready and can make use of mutiple CPUs where available. JAS can run on a wide variety of devices ranging from Android (using the jruby Ruboto App and others) to compute clusters (using MPJ a Java Message Passing Interface (MPI)).

This package contains example adapters to the Python scripts of Ebert and Perry for the computation of signature based Gröber base algorithms.

See introduction for a general overview.

The original Python - Sage - Singular scripts from Eder and Perry are available at http://www.math.usm.edu/perry/Research/basic_sigbased_gb.py. The scripts for JAS are verbatim the same with two small modifications.
