A Kantorovich Version of Bernstein‐Type Logarithmic Operators
Mathematische Nachrichten, EarlyView.ABSTRACT In this paper, we introduce a Kantorovich version of the Bernstein‐type logarithmic operators. The idea comes from the wide literature concerning exponential polynomials that preserve exponential functions: here, the exponential weights are replaced by logarithmic ones and the corresponding operators preserve the logarithmic functions.

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 ...

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 ...

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$L$.

Materials Genome Engineering Advances, EarlyView.Crystal‐plasticity phase‐field simulations combined with stacked machine learning map the creep microstructure relationship in lamellar Ti‐Al alloys. Interpretable learning identifies lamellar thickness, elastic strain energy, and interfacial energy as dominant factors governing the diffusion‐to‐dislocation creep transition and overall creep resistance.

Mathematical Methods in the Applied Sciences, EarlyView.A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...
