@user118494 Just out of curiosity I want to ask. Are you a PhD student of somebody who works in ideal convergence and related topics? (Feel free to ignore the question if you want simply want to protect your privacy and remain as anonymous on this site as possible.)

I know that there are several people working on related topics in India, Turkey and in Poland. (And probably many other countries.) I am not a native speaker myself, so this is difficult for me to judge, but by noticing some expressions in your phrasing of things, if I had to guess I would say India.

BTW to respond to your "triviva" question:

No I have not met Brian M. Scott. In fact, there are hardly any users from this site which I have met personally. (This is difficult to say for people who remain anonymous, but some users use their real names here.)

There are two users I know personally which used this site a few times and I was the person who told them about Math.SE and suggested that it might be useful for what they are interested in.

There are few others from Slovakia, we do not know each other too well, but at least we know about each other and we have seen each other a few times.

Since you are interested in I-convergence: From the people working in this topic I have met one or two at conferences I've attended. (Here I do not count people from Slovakia - of course people from the same area which work on similar topics know each other.) And, of course, I have also met in person the people who are coauthors in some of my papers. (However, only some of them are on I-convergence.)

@MartinSleziak Remember that piecewise continuity stuff I was doing before? I tried seeing if it works for solving differential equations. Some of the forms are weird (like how homogeneous linear equations have different things depending on the roots) because I am replacing constant coefficients with piecewise coefficients but I found in the last 24-48 hours or so that I'm no longer dealing with "find a specific piecewise constant c(x) such that f(x) = g(x) + c(x) is continuous".

I'm dealing with unknown c(x) piece wise constant functions virtually everywhere you can imagine. It is amazing how many natural logarithms it takes to pull them apart into the additive version of the functional equation.

Oddly enough... it's actually starting to become fun again.

@TheGreatDuck I remember your posts, although I did not understand them.

I have noticed that you have started a new chatroom:

chat.stackexchange.com/rooms/47438/implied-calculus-room

An alternative solution would be to unfreeze the old one:

Of course, if you think that in the old room there was nothing which was actually of interest, then unfreezing it is not that useful.

The same is true if the topics of the two rooms are totally unrelated.

IIRC Eric Stucky had a go on answering some of your questions.

I'll have to go AFK now for a bit and then I will go offline and go to work.

@MartinSleziak I think Eric Stucky understood my posts more than I understood my posts.

@MartinSleziak yes, unfreezing the old chatroom is probably preferred.

@TheGreatDuck If there is a room which somebody want to unfreeze, the standard approach is ask some moderator whether they will be willing to do that. How do I unfreeze a frozen chat room?

I flagged the frozen notification and asked if it be unfroze.

@MartinSleziak Basically Martin, I made up a completely different antiderivative, and surprisingly... it's brand of differential equations evaluate identically to regular differential equations (barring situations where constants cannot be unknown of course).
