MaplePrimes Announcement

Some of you know me from my occasional posts on Maple’s typesetting and plotting features, but today, I am here in my new role as co-chair (along with Rob Corless of Western University) of the 2021 Maple Conference. I am pleased to announce that we have just opened the Call for Presentations.

This year’s conference will be held Nov. 2 – Nov. 5, 2021. It will be a free virtual event again this year, making it an excellent opportunity to share your Maple-related work with others without the expenses and inconveniences of travel.

Maple Conference 2021 invites submissions of proposals for presentations on a range of topics related to Maple, including Maple in education, algorithms and software, and applications. All presenters will be given the option of submitting a full paper, which will undergo peer review, and if accepted, be included in the conference proceedings.

Presentation proposals are due June 1, 2021.

You can find more information about the themes of the conference, how to submit a presentation proposal, and the program committee on Maplesoft Conference Call for Presentations.

Registration for attending the conference will open in June. Another announcement will be made at that time.

I sincerely hope that all of you here in the Maple Primes community will consider joining us for this event, whether as a presenter or attendee.

The site contains free books in English and Russian along with software created under the guidance of the main author prof. V. Aladjev in such areas as general theory of statistics, theory of cellular automata, programming in Maple and Mathematica systems. Each book is archived, including its cover and book block in pdf format. The software with freeware license is designed for Maple and Mathematica.

CMRB is defined below. See

Starting by using Maple on the Inverse Symbolic Calculator, with over 21 years of research and ideas from users like you, I developed this shortlist of formulas for the MRB constant.

  • CMRB= eta equals enter image description here

That is proven below by an internet scholar going by the moniker "Dark Malthorp:"

Dark Marthorp's proof


  • eta sums denoting the kth derivative of the Dirichlet eta function of k and 0 respectively was first discovered in 2012 by Richard Crandall of Apple Computer.

The left half is proven below by Gottfried Helms and it is proven more rigorously considering the conditionally convergent sum,enter image description here below that. Then the right half is a Taylor expansion of η(s) around s = 0.



it has been noted that "even though one has cause to be a little bit wary around formal rearrangements of conditionally convergent sums (see the Riemann series theorem), it's not very difficult to validate the formal manipulation of Helms. The idea is to cordon off a big chunk of the infinite double summation (all the terms from the second column on) that we know is absolutely convergent, which we are then free to rearrange with impunity. (Most relevantly for our purposes here, see pages 80-85 of this document, culminating with the Fubini theorem which is essentially the manipulation Helms is using.)"
