    • Property Summary changed from Meta-Ticket: Asymptotic Expressions in Sage to Meta-Ticket: Asymptotic Expansions in SageMath
  • Ticket #17601 – Description

    v31 v33  
    2626    * #17716 (!AsymptoticRing and !AsymptoticExpression): sum of asymptotic terms.
    2727
     28* Extending the functionality of growth groups
     29    * #19028: More growth group implementations: exponential growth groups.
     30    * #18587: cartesian products for growth groups (allowing the construction of more complicated univariate as well as multivariate asymptotic expressions)
     31        * #18223: cartesian products with orders
     32        * #18586: passing on parameters and extra_category for cartesian products
     33        * implement dependencies like |k| <= n^1/2^ for different growth group variables.
     34
    2835* Extending the functionality of the !AsymptoticRing and !AsymptoticExpression
    29     * #19017: Easy access to the `O`-constructor in `big_oh.py`.
    3036    * #19068: Implement Division for asymptotic Expressions.
    3137    * #19094: Implement higher-order operations like `exp` and `log` for asymptotic expressions.
    32     * Improve the user interface: extend the conversion from the symbolic ring such that more than just monomials can be converted.
    33     * Implement comparison for asymptotic expressions.
    34     * Improve the performance of computations in the !AsymptoticRing.
    3538    * #19048: `AsymptoticRing.an_element()`

    48 
    4945* Further plans
    5046    * growth groups with asymptotic at a non-infinity point
     47    * Deal with comparison for asymptotic expressions.
     48    * Check and improve the performance of computations in the !AsymptoticRing.
    5149    * Implementation of more types of asymptotic terms (little-oh terms, omega-terms, variations of big-Oh terms ...)
    5250
    53 
    5451* Additional Dependencies:
     52    * #19017: Easy access to the `O`-constructor in `big_oh.py`.

    5654    * #19110: QQ(0)^-1 raises SIGFPE (which is caught)
