[sage-devel] About the "show" function

[Furkan Semih Dündar]

Dear All,

Recently I had to do some calculations regarding the Killing vector fields. 
When I used "show" command to display equations (which define the KV's) 
involving derivatives I was not satisfied with what was displayed. Although 
the differential equations were correct.

There are many conventions for displaying functions whose derivatives are 
taken. The default one in the show function, I think, should remain 
default. On the other hand, \partial_x f(x,y) types of expressions may be 
useful in some scenarios. Or the subscript notation f_x to denote the 
derivative with respect to x. Perhaps one may also like to hide the 
arguments of functions.

I would like to add these functionalities to sagemath in my free time. 
However I am not familiar at the moment with the sagemath source code. If 
this idea seems plausible for you, could you point me to a place in which 
show command is located?

Best regards,
Furkan Semih.

Re: [sage-devel] Fourier series expansion function: fourier_expand()

[Furkan Semih Dündar]

Yes. The function (fourier_series_partial_sum) is what I have in mind. Glad
to see that it is implemented.

Best.

[sage-devel] Fourier series expansion function: fourier_expand()

[Furkan Semih Dündar]

Dear All,

I want to implement an easy function (afaik is lacking in Sage Math) that
may be called as "fourier_expand" which will return Fourier series of a
function (for which integrals can be calculated analytically) up to some
order N. If integrals cannot be calculated analytically, numerical
integration might be used, perhaps.

I am looking for a suitable place to put this function in /src/sage
directory.

Any suggestions?

Re: [sage-devel] Developing in Sage for high school math education

[Furkan Semih Dündar]

I have just seen the project "penrose-python" apart from the "penrose"
project.

https://github.com/penrose/penrose-python

If there is enough development of this package, I will be (maybe) able to
write a SageMath wrapper for "penrose".

Currently it is "Not ready for use".

Best.
Furkan Semih.

Re: [sage-devel] Developing in Sage for high school math education

[Furkan Semih Dündar]

As far as I am aware, no. I may be interested in doing so if we can form a
small group. And in that way we can contribute to Sage developement though
it would be something moderate. However at the moment I do not know how to
write a wrapper for Penrose. Maybe we can learn how to contribute once we
are on the road.

All the best.

Re: [sage-devel] Developing in Sage for high school math education

[Furkan Semih Dündar]

I may be late to the discussion but as regards the Venn Diagrams there is
an early stage software you might find useful:

https://penrose.cs.cmu.edu/
https://github.com/penrose

It might be incorporated in to Sage (maybe?).

Just wanted to add a quick note.

[sage-devel] About numerical solutions of high order (>= 2) ode's

[Furkan Semih Dündar]

Dear All,

I opened a ticket a few months ago: https://trac.sagemath.org/ticket/29915

The basic idea is that Sage should be able to solve an n'th order ode
numerically without the user defining it as a system of n 1st order ode's.

I have free time in the upcoming weeks and would like to contribute this
feature/code.

However I don't know where to start. Should I download the source code of
the latest stable version or the latest beta version?

Can I make this development under MS Windows or Linux? I have a Fedora
installation, so if Linux is required this is no problem.

Last but not least, suppose I changed the required part of the Sage code.
Should I compile the whole code or is there a way to patch just the
difference in the code?

Best regards,

[sage-devel] Lie symmetries of differential equations

[Furkan Semih Dündar]

 Dearl All,

I recently bought the book that I studied in my PhD years. It is "*Differential
Equations: their solution using symmetries*" by Hans Stephani.
https://www.amazon.com/Differential-Equations-Their-Solution-Symmetries/dp/0521355311/ref=sr_1_1?dchild=1=hans+stephani+differential+equation=1591870417=8-1

In the book, methods to solve nonlinear ODE's or PDE's are given if the
differential equation has an underlying Lie group symmetry. I remember
using the program "Reduce" in the course. It may be useful.

My aim is to incorporate the methods given in the book to Sage Math. So if
you are interested maybe we can form a small group to contribute to Sage in
this respect. I believe the ability to solve complex differential equations
is quite important for a symbolic math software. Please let me know if you
are interested.

Best regards,

Re: [sage-devel] Re: trouble upgrading to latest stable version

[Furkan Semih Dündar]

Dear Anne,

I tried to compile the source code on Windows Subsystem for Linux (Ubuntu)
and could not go through the compilation process. Then I installed Fedora
32 as a separate OS. I installed all the packages listed on the following
website:
https://doc.sagemath.org/html/en/installation/source.html#prerequisites

Then I let my computer compile the source code at night, when I woke up it
was compiled successfully.

Hope this might help.

Best wishes,
Furkan.

Re: [sage-devel] Physics related tutorials

[Furkan Semih Dündar]

Dear Thierry,

I was unaware of sagemanifolds web page. It already includes many decent GR 
related tutorials. When I was a MSc student I remember using Eric's lecture 
notes on 3+1 formalism in GR.

You are right, perhaps it is best to write the tutorials first.

Thanks for the advice.

Best wishes,
Furkan.

[sage-devel] Physics related tutorials

[Furkan Semih Dündar]

Dear All,

My name is Furkan Semih Dündar.

I am a new member of the group and a physicist in Turkey. So I would like 
to contribute physics related tutorials to the Sage web page.

The topics may include classical mechanics (Lagrangian and Hamiltonian), 
quantum mechanics (matrix mechanics and the Schrödinger equation), General 
relativity (if I figure out how to do tensor calculus on Sage) and so on.

I downloaded the source code for the version 9.1 and compiled it last night 
on Fedora 32.

Are there any suggestions on how to organize the tutorials? For example 
should I open a separate topic on physics or include the physics related 
applications on math related topics? (For example classical mechanics in 
differential equations?)

Best wishes,
Furkan.
