Gröbner BasesIn this lecture we shall consider (in a slightly vulgarized form, without rigorous mathematical terms) an important mathematical achievement of the second half of the last century—Gröbner bases, the Buchberger algorithm (which constructs them), and their applications (see [12, 13] for an introduction).

Input–Output and StringsWhen developing any nontrivial . program, it is better to write it in a text file, using a text editor, and then to read it into a fresh . session. In this way, your actions will be reproducible. You can fix a bug and see what has changed. Suppose we have a text file called wrong.m. It contains the text
