Re: [sympy] Multivariate Resultants

Thank you for your reply Aaron. 
I believe that the multivariate resultants are a good follow up from what 
is already within the library,

I will go ahead and open a pull request.

Kind regards
Nikoleta

[sympy] Multivariate Resultants

2018-02-10 Thread Nikoleta-v3


Hello all

My name is Nikoleta Glynatsi. I am a PhD student at the School of 
Mathematics, Cardiff University. My field of research is Game Theory and I 
am software developer. 

I have received a fellowship from the Software Sustainability Institute 
<https://software.ac.uk/>, I am a contributor to the Axelrod Python 
<https://github.com/Axelrod-Python> library and the main developer of Arcas 
<https://github.com/ArcasProject/Arcas>, a python tool designed to help 
with collecting academic articles from various APIs.

I have been working with the programming language Python for the past two 
years and I am an active member of the community. I have at attended  PyCon 
UK 2016, 2017 and Pycon Namibia 2017. I have given talks to all these 
events (https://nikoleta-v3.github.io/talks/) and I am one of the 
organisers of Django Girls UK.

I’ve been using SymPy regularly for my research for the past two years. One 
of my recent areas of focus has been resultant theory. There are a few 
resultants implemented within the SymPy such as, Sylvester's and Bezout’s

(
https://github.com/sympy/sympy/blob/master/sympy/polys/subresultants_qq_zz.py
).

However, there are not any multivariate resultants within the library.

I have implemented the following two multivariate resultants,

   - 
   
   Dixon's. Reference: https://dl.acm.org/citation.cfm?doid=190347.190372 
   - 
   
   Macaulay's. Reference: https://dl.acm.org/citation.cfm?id=550525 
   

The source code is available on GitHub: 
https://github.com/Nikoleta-v3/resultant-theory and I have also written 
suitable tests for each implementation.

I understand that the SymPy team would prefer contributions to already 
existing code or work on ideas that are listed on the Project Ideas Page 
<https://github.com/sympy/sympy/wiki/Project-General-Ideas>.

However, I was wondering if you would find any of the above resultants 
useful and would be interested in adding them to the library.

Thank you very much for your time.

Kind regards

Nikoleta
