Nonconstant Positive Steady States for a Predator–Prey System With Signal‐Dependent Diffusion

Mathematische Nachrichten, EarlyView.
ABSTRACT This paper investigates a highly nonlinear predator–prey reaction–diffusion system featuring signal‐dependent prey diffusion, where the motility of the prey is modulated by a chemical signal released by predators. For unbounded functional responses, we establish the global‐in‐time existence and uniform‐in‐time boundedness of classical ...

Graded Differential Polynomial Rings

Mathematische Nachrichten, EarlyView.
ABSTRACT We study differential polynomial rings R[t;δ]$R[t;\delta]$ over Γ$\Gamma$‐graded rings, where Γ$\Gamma$ is an arbitrary group. We show that R[t;δ]$R[t;\delta]$ admits a Γ$\Gamma$‐grading compatible with that of R$R$ if and only if δ$\delta$ is a γ$\gamma$‐derivation for some γ∈CΓ(ΓR)$\gamma \in C_\Gamma (\Gamma _R)$, and that this grading is ...

The Reduction Theorem for Leavitt Path Algebras of Labeled Graphs and Its Applications

Mathematische Nachrichten, EarlyView.
ABSTRACT We introduce a notion of labeled cycle for normal labeled spaces and prove a reduction theorem for Leavitt path algebras associated with labeled graphs. We show that every nonzero element can be reduced, by suitable left and right multiplication, either to a nonzero scalar multiple of a projection or to a polynomial supported on a labeled ...

Unexpected Primes of Good Reduction in Quotients of Modular and Shimura Curves

Mathematische Nachrichten, EarlyView.
ABSTRACT We find all zero‐dimensional spaces of newforms of weight 2 and squarefree level N$N$ with a fixed Atkin–Lehner sign pattern. As an application, we classify unexpected primes of good reduction of Atkin–Lehner quotients of modular and Shimura curves of squarefree levels.

On Symmetries of Hyperbolic Lattices of Large Rank

Mathematische Nachrichten, EarlyView.
ABSTRACT For an even, integral hyperbolic lattice L$L$, the symmetry group of L$L$ is the quotient of the group of positive isometries of L$L$ by the Weyl subgroup of (−2)$(-2)$‐reflections. Following Nikulin, the exceptional lattice of L$L$ is defined as the sublattice generated by elements that have finite orbit under the symmetry group of L$L$.
