Hello guys , I am working on couple of Pr's extending the functionality of the doit method in the concrete module , I noticed that one inconsistency leads to couple of errors . Product(1, (n, 1, oo)).doit() returns 1 and 1**oo returns NaN. Other integers work as expected . These expressions are

[sympy] Is gruntz expected to work properly for factorial2 (Double factorial) ???

I caught this while trying to execute the is_convergent() method from the concrete module for Sum . So the problem is that any expression of the form Sum( f(x), (x, 1, oo)).is_convergent() where f(x) contains factorial2 either gives out an error or False. Some examples being >>> Sum(factorial

Hello All, I've updated the ideas for the topic "Improving Series Expansions & Limit Computations" (which is the project I worked on during GSoC 2022) for GSoC 2024. I think I've explained it enough for anyone to understand and frame a proposal. If anyone has any doubts they could reach out to

[sympy] Re: In memory of Kalevi Suominen

Hello All, This is very sad to hear for me. Being someone who worked with him for like 6 - 8 months (Oct 2021 - Apr 2022 while I used to contribute to the Series & Limits module and May 2022 - Aug 2022 while Kalevi was my GSoC Mentor) , I can say that this is a huge loss for the community. If y
