Det är på något vis en stor sorg för mig att Sommar i P1 inte längre erbjuds som podcast. Sverige Radio vill att man lyssnar i SR Play-appen. Alltså inte alls via det öppna format som är podcastens signum. Och det är såklart inte “podd” oavsett om man väljer att fortfarande kalla det så.

Visst, du kan lyssna online också, men det är ju inte direkt byggt för att hålla dina avsnitt i ordning. Eller för att kunna hålla sitt lyssnande till en app.

Ändå. End rant. Dags för Petra Me…

De afdeling klimaat van CEO, Corporate Europe Observatory, heeft lezenwaardige stukken. Het eerste stuk gaat over de Europese plannen voor groene waterstof en de lobby van Big Oil om daar met hun vuile handen aan te zitten en zo bakken subsidie binnen te harken.

Finally got a good picture of Bob B, the stray cat that I tried to gentle last year who's now coming around our barn. He let me feed him a few times but then he rolled on his back and then bit me when I moved my hand too close. My wife is still feeding him and he likes watching horse lessoners so I have hope he'll come around

On Banach subalgebras of $\mathscr{H}^\infty$ consisting of lacunary Dirichlet series
Let $\mathscr{H}^\infty$ be the set of all Dirichlet series $f=\sum_{n=1}^\infty a_nn^{-s}$ (where $a_n\in\mathbb{C}$ for all $n\in\mathbb{N}=\{1,2,3,\cdots\}$) that converge at each $s$ in $\mathbb{C}_0=\{s\in \mathbb{C}:\text{Re}(s)>0\}$, such that $\|f\|_{\infty}=\sup_{s\in\mathbb{C}_0}|f(s)|<\infty$. Then $\mathscr{H}^\infty$ is a Banach algebra with pointwise operations and the supremum norm $\|\cdot\|_\infty$, and has been studied in earlier works. The articl…

On non-linear chiral 4-form theories in D=10
We consider properties of non-linear theories of a chiral 4-form gauge field $A_4$ in ten space-time dimensions with an emphasis on a subclass of these theories which are invariant under the $D = 10$ conformal symmetry. We show that general results regarding a peculiar structure of duality-invariant abelian gauge theories in four and six space-time dimensions do not extend to non-linear chiral 4-form theories in ten dimensions. This discrepancy arises primarily from the large number 81 of indep…

Some remarks on invariants
The demand to know the structure of functionally independent invariants of tensor fields arises in many problems of theoretical and mathematical physics, for instance for the construction of interacting higher-order tensor field actions. In mathematical terms the problem can be formulated as follows. Given a semi-simple finite-dimensional Lie algebra $\mathfrak g$ and a $\mathfrak g$-module $V$, one may ask about the structure of the sub-ring of $\mathfrak g$-invariants inside the ring freely g…
