I'm moving to a different mastodon server: mathstodon.xyz

This server also has some LaTeX support for posts.

Leiden Declaration on Artificial Intelligence and Mathematics

This declaration calls for action to address the challenges posed by the use of artificial intelligence within mathematics research.

We extended the numerical approximation scheme for modular Hamiltonian in quantum field theory and got new results for fermionic fields:

Numerical approach to the modular operator for fermionic systems

We numerically approximate the Tomita-Takesaki modular operator for local subalgebras of the 1+1-dimensional massive Majorana field. Our method works at the one-particle level with a discretisation of time-0 data in position space. The local subspaces we consider are associated with one double cone and with the disjoint union of two double cones. In order to avoid boundary effects, we primarily choose the overall spacetime to be a cylinder; different choices of boundary conditions (antiperiodic and periodic) are considered. We compare our numerical results to known analytic expressions in the massless case. It turns out that the modular operator has a non-trivial dependence on the mass. In the case of two double cones, the modular generator does not only have ''local'' contributions (supported on the diagonal in configuration space) but also ''bilocal'' terms (connecting the two double cone regions); we find the latter to be less prominent at higher masses, in line with expectations.

AI could destroy mathematics and barely touch it
https://davidbessis.substack.com/p/the-fall-of-the-theorem-economy
#AI challenges the "theorem economy" by automating #proofs while overlooking human intuition. Bessis argues that math's true product is understanding, not just results, which AI cannot yet replicate. The discipline's focus on theorems over concepts makes it vulnerable to machines that solve problems without building meaning. To remain relevant, mathematicians must emphasize the field's role in human sense-making rather than competitive symbol-pushing. Success depends on valuing the process of cognitive elevation and the creation of shared conceptual language.

"One reason why mathematics enjoys special esteem, above all other sciences, is that its laws are absolutely certain and indisputable, while those of all other sciences are to some extent debatable and in constant danger of being overthrown by newly discovered facts." – Albert Einstein (1879-1955)

Ist das ein Versuch von Söder die #soderchallenge anzugehen?

CSU-Chef Söder fordert Rückkehr zur Atomkraft mit Mini-AKW in Bayern

Die EU will wieder verstärkt in Atomkraft investieren. CSU-Chef Markus Söder unterstützt das auch für Deutschland - und schlägt ein Pilotprojekt in Bayern vor. In der Regierung ist das Thema jedoch umstritten.

Keep Android Open

Because Android is open, for now, till 01 September 2K26, I have been able to install this wonderful tool set of which you see a screen cap below.

If all of you who read this toot, please boost for visibility, make your voices heard as it is explained in the first link, you will be able to stop Google from closing Android worse than Apple

We all need to unite to stop google cold in their tracks

EU users have enormous power in this, remember USB-C on apple

Don't think you don't have power to stop google

UNITE!
