The goal of this project was to extend SageMath with support for error terms with explicit constants to AsymptoticRing. We called these terms B-terms. Adding support was done in a modular fashion. Every ticket on the Trac-Server of SageMath represents a functional part of this project. These modules contain the initial support and different growth groups supported by AsymptoticRing.
At the end of the project we got a working product which enables SageMath users to do calculations like:
sage: A.<n> = AsymptoticRing('n^QQ', QQ)
sage: n^2 + A.B(n, valid_from=1) + 41
n^2 + B(42*n, n>=1)
