Time dilation and dynamical systems go well together!

By moving faster or slower along a system's trajectory, you change the dynamic of the system (but not its geometry!), and, in some cases end up with a linear system (up to a change of coordinates)!

Even if the function γ depends on the state of the system, time-rescaling is an interesting way of building non-linear observers from a Luenberger observer.

hey :)

that's where I'll post whatever math thingy I want to share!

you can expect:

differential geometry

control theory

functional analysis

differential equations

and some computer science too :)

here's a bonus stoke's theorem :

\\[\int_M d\omega = \int_{\partial M} \omega\\]
