Hynek Did Something
Greetings friend! This is a list for those who’d like to be notified whenever Hynek Schlawack does or publishes something noteworthy, somewhere. Examples are new blog posts, YouTube videos, and talks, or significant updates to existing work. It does not include announcements about new software releases. As a thank you for your trust, the emails aren’t just links to content. They contain a kind of “director's commentary”, explaining what I did and why – written as if I’d be explainin…

Wie der Bundesverband Solarwirtschaft mitteilt, haben wir die Hälfte des Weges zum Ausbauziel 2030 bereits geschafft. Aktuell sind etwa 107,5 Gigawatt an Solarleistung installiert - das Ziel liegt bei 215 Gigawatt.

We spoke to several people on the House GOP whip team Tuesday night who were expressing alarm about what they’re seeing on their whip cards.
These sources said that they were racking up no’s from lawmakers who they didn’t expect would be opposed to the bill.
Again, it is likely the bill passes in the next 24 hours
but as we learned with the Trump’s failed effort to repeal the ACA in 2017 nothing is pre-ordained in this business,
and we just have to keep working as ha…

Generative Lagrangian data assimilation for ocean dynamics under extreme sparsity
Reconstructing ocean dynamics from observational data is fundamentally limited by the sparse, irregular, and Lagrangian nature of spatial sampling, particularly in subsurface and remote regions. This sparsity poses significant challenges for forecasting key phenomena such as eddy shedding and rogue waves. Traditional data assimilation methods and deep learning models often struggle to recover mesoscale turbulence under such constraints. We leverage a deep learning framework that combines neural…

On Generators of Bloch groups of CM fields
This article generalizes the result of Burns et al (2022), to find an algorithm to find some elements generating a full-rank subgroup of the torsion-free part of Bloch group of a certain CM number field, and compute the rank of it.

On the Complexity of Problems on Graphs Defined on Groups
We study the complexity of graph problems on graphs defined on groups, especially power graphs. We observe that an isomorphism invariant problem, such as Hamiltonian Path, Partition into Cliques, Feedback Vertex Set, Subgraph Isomorphism, cannot be NP-complete for power graphs, commuting graphs, enhanced power graphs, directed power graphs, and bounded-degree Cayley graphs, assuming the Exponential Time Hypothesis (ETH). An analogous result holds for isomorphism invariant group problems: no suc…
