Re: [GiNaC-devel] web page

Dear Colleagues, I think that it may be time to patch the GiNaC web page. The passed months showed that the situation is much more complicated and dangerous than we may think back in March. Current information flows are full of fakes, manipulations and war-time propaganda. The sequence of events will be a subject for heated debates for decades to come. Yet, I cannot see a side which is advocating an end of the war unless it will be their complete victory. Deaths and suffering of Ukraine population are not considered as an obstacle towards the designated goals. Thus I propose to delete the following sentences from the statement: "We must make the Russian government understand the value and prospect of peaceful cooperation and end this war now." Also I propose to leave the previous sentence "We strongly support the call for peace in Ukraine." but without the link in it. In my opinion, the quoted letter is not free from a bias which reduces the peaceful call in the sentence. Alternatively, we may delete the whole statement all together. Calling for peace we shall do the first step ourselves by not taking a side in the ongoing war. Best wishes, Vladimir -- Vladimir V.

info() methods for transcendental functions
by Vladimir V. Kisil 10 Sep '22

10 Sep '22

Dear Colleagues, I am proposing a small patch which provides some elementary info() methods to GiNaC predefined transcendental functions. Only easy answers are sought, which can be decided on info tests of the functions arguments. From such coarse viewpoint functions are grouped into several classes and the respective routines can be shared. Best wishes, Vladimir -- Vladimir V.
