The question is really about $\ell^p$ space and the $L^p$ space tag is good enough. I've untagged it.

Q: Should MSE actively (structurally) encourage questions which disseminate information across specialties?

Over the past month, I have used (and perhaps abused) both MSE and MO in order to obtain certain purely mathematical information of critical importance to my team at this point in its research trajectory. In the course of doing so, I have posted questions like this one at MSE: Is there an inter...

The tags switchedsystem and statespace have been removed from this question, but soon the too tags appeared again.

Q: understanding solution of state equation

Could anyone help me to understand that how the solution of $(1)$ is written as in $(2)$? I know that $\dot x=Ax+Bu$ is $x(t)=e^{At}x(0)+\int_{0}^{t} e^{A(t-s)} Bu(s)ds$ Edit: After the pauls answer: Here I will have solutions in each subintervals as follows? $x(t)=e^{A_{i_0}t}x(t_0)+\int_{t...

It seems that some users are thinking about introducing a few new tags:

You can give your questions up to five tags. You can tag your question algebraic-groups and also tag that same question polytopes and also tag it root-systems and also tag it cross-specialty and also tag it pain-in-the-butt, if you like. So what is the point of your question? — Gerry Myerson 1 hour ago

Q: Almost surely tag

We have a almost-everywhere tag for measure-theory. Do we need "almost-sure" tag for probability space? The later is a particular case of the former, but the later concerns a vast variety of topics in probability-theory, such as Hewitt–Savage zero–one law, etc, that won't be seen in questions ...
