With my article from https://karl-voit.at/2025/09/14/fix-wrong-34-TFT-resolution/ I published an engineering task via my blog.
Independent of the content, this is an example how I typically write down notes on almost everything I have to deal with on a computer.

Complete Non-Selfadjointness of Extensions of Symmetric Operators with Bounded Dissipative Perturbations
Using boundary triples, we develop an abstract framework to investigate the complete non-selfadjointness of the maximally dissipative extensions of dissipative operators of the form $S+iV$, where $S$ is symmetric with equal finite defect indices and $V$ is a bounded non-negative operator. Our key example is the dissipative Schrödinger operator $-\tfrac{d^2}{dx^2}+\mathrm{i} V$ on the interval.
