Show HN: Sostactic – polynomial inequalities using sums-of-squares in Lean
via news.ycombinator.com
Short excerpt below. Read at the original source.
Current support for nonlinear inequalities in Lean is quite limited. This package attempts to solve this. It contains a collection of Lean4 tactics for proving polynomial inequalities via sum-of-squares (SOS) decompositions, powered by a Python backend. You can use it via Python or Lean. These tactics are significantly more powerful than `nlinarith` and `positivity` — […]
