most of them are valid and some only semi-valid: 1. Multivariate polynomials and factorization Done in principle be could be better, as stated in the text. 2. Univariate polynomials over algebraic domains Work in progress in polys5. 3. Assumptions, formal logics etc. Partially done last year but needs significant improvements. And a few comments (assuming bold ones are important): 1. Integrate our experimental Cython core into SymPy NO, first do it the right way in pure Python. 2. Add support for solving inequalities, and ... This should be top priority this year. However, the problem itself is huge and requires a lot of work, mostly because one will need to implement cylindrical algebraic decomposition. If this will be done then it will be possible to implement reasoning algorithms in R^n, quantifier elimination ... 3. Improve the series expansion Would be cool, clean up the mess, make it fast, implement other types of series. I will update and expand the detailed ideas list in spare time. -- Mateusz
