Berliner Bildungsverwaltung will kein Handyverbot, setzt auf Eigenverantwortung
In einigen Bundesländern wird das Schulgesetz für Handyverbote angepasst, in Berlin wird es den Schulen überlassen, wie sie mit der Streitfrage umgehen.

Excellent news. Greatly reduces the risk of displacement while still upzoning the west side.

Most rent-controlled buildings to be exempted from S.F. upzoning plan
Mayor Lurie makes a deal with Myrna Melgar, D7 supe who criticized lack of tenant protections in zoning plan.

Reducing (some of) the #EV benefits is never a popular measure. Perhaps that is why it is being introduced now, after the recent elections.
At the same time, the incentive remains in place, because the purchase tax on fossil fuel engines is also increasing, as are fuel taxes.

Invariant subspace perturbations related to defective eigenvalues of $Δ$-Hermitian and Hamiltonian matrices
Structured perturbation results for invariant subspaces of $Δ$-Hermitian and Hamiltonian matrices are provided. The invariant subspaces under consideration are associated with the eigenvalues perturbed from a single defective eigenvalue. The results show how the original eigenvectors and generalized eigenvectors are involved in composing such perturbed invariant subspaces and eigenvectors.

Tricyclic graphs for which the second largest distance eigenvalue less than $-\frac{1}{2}$
Let $G$ be a simple connected graph with vertex set $V(G)=\{v_{1}, v_{2}, \ldots, v_{n}\}$. The distance $d_G(v_i,v_j)$ between two vertices $v_i$ and $v_j$ of $G$ is the length of a shortest path between $v_i$ and $v_j$. The distance matrix of $G$ is defined as $D(G)=(d_G(v_i,v_j))_{n\times n}$. The second largest distance eigenvalue of \( G \) is the second largest eigenvalues of $D(G)$. Guo and Zhou [Discrete Math. 347(2024), 114082] proved that any connected graph with the second largest di…

IGA Laplace Eigenfrequencies Distributions and Estimations: Impact of Reparametrization on Eigenfrequency Behavior
This work addresses the Galerkin isogeometric discretization of the one-dimensional Laplace eigenvalue problem subject to homogeneous Dirichlet boundary conditions on a bounded interval. We employ GLT theory to analyze the behavior of the eigenfrequencies when a reparametrization is applied to the computational domain. Under suitable assumptions on the reparametrization transformation, we prove that a structured pattern emerges in the distribution of eigenfrequencies when the problem is reframe…
