Description (last modified by )
We intend to implement asymptotic expansions in SageMath. We would like to do computations with simple expansions such as
n^{2} + n^{3/2} + O(n^{1/2}),
but also with expansions such as
2^{n} * n + O(n*log(n))
or even multivariate expansions such as
3*k/n + O(k^{2} / n^{2}) with k <= n^{(1/2)}.
Of course, O(n)  O(n) = O(n) must hold and we want to perform various arithmetic operations with these asymptotic expansions. Eventually, specified Oconstants shall also be supported.
See #17716 and #19083 for more examples and the documentation files there for a more detailed description. A working prototype can be found in branch u/dkrenn/asy/prototype
.
Roadmap:
 Implementing a minimal working example
 #17600 (AsymptoticGrowthElement): elements which handle the asymptotic growth. Such an element holds, e.g. n^{2} or k/n or n*log(n). This can compare, multiply etc., but has no coefficient; the order of magnitude is managed here. Concretely for this ticket: MonomialGrowthElement, implementation for powers.
 #18930: Factory for userfriendly generation of growth groups
 #17715 (AsymptoticTerm): a summand for asymptotic expansions. They contain the growth and additional information on the type of the summand. For starters, there will be bigOh terms (e.g.
O(n)
and exact terms (e.g.3*n^2
).  #17693 (MutablePoset): data structure for storing asymptotic terms within an asymptotic expansions.
 #17716 (AsymptoticRing and AsymptoticExpansion): sum of asymptotic terms.
 Extending the functionality of growth groups
 Extending the functionality of the AsymptoticRing and AsymptoticExpansion
 #19048:
AsymptoticRing.an_element()
 #19068: Implement Division for asymptotic expansions.
 #19073: categorial constructions, pushout and coercions (extended) for asymptotic ring and growth groups
 #19094: Implement higherorder operations like
exp
andlog
for asymptotic expansions.  #19083: AsymptoticRing: cleanup, some improvements, documentation.
 #19400: move code to sage.asymptotic
 #19048:
 Bugs and minor improvements
 Further plans
 for growth groups
 implement dependencies like k <= n^{1/2} for different growth group variables.
 growth groups with asymptotic at a noninfinity point
 other
 Deal with comparison for asymptotic expansions.
 Check and improve the performance of computations in the AsymptoticRing.
 Implementation of more types of asymptotic terms (littleoh terms, omegaterms, variations of bigOh terms ...)
 #19300: Run benchmarks on
MutablePoset.remove
to decide between two algorithms.  #19305: substitution of asymptotic expansions
 #19306: common generators for asymptotic expansions
 #19259: subrings of the symbolic ring
 #19316 compute asymptotic expansion to some rational directly
 for growth groups

Are "asymptotic expressions" equivalent to "transseries" (http://arxiv.org/abs/0801.4877, http://www.texmacs.org/joris/ln/lnabs.html)? Or are they more general, less general, or partially overlapping in scope?

comment:13 followup: ↓ 14 Changed 6 years ago by
Hi,
Whatever you propose, I would say that the most important thing to do is to consider the integration into Sage. In other words:
 how it will be used from Sage
 how it does interact with the Symbolic ring, polynomials, fraction fields, power series and any objects where asymptotic makes sens
I do not see any of this in the ticket description. And it is definitely important to think of it before starting the implementation.
I only see a list of classes, parents and elements whose goal is basically to mimic the symbolic ring by adding some big Oh. I do not see the point of creating so much classes to handle asymptotic terms. Please, motivate and explain your choices.
Vincent

Replying to vdelecroix:
I only see a list of classes, parents and elements whose goal is basically to mimic the symbolic ring by adding some big Oh.
I rather think of it as a version of the PowerSeriesRing
with additional features (noninteger exponents, several (not completely independent) variables).
