Representation of the norming constants by two spectra
Electronic Journal of Differential Equations, 2010 The representation of the norming constants by 2 spectra was studied by Levitan, Gasymov (and others) for the Sturm-Liouville problem with boundary conditions $y(0)cosalpha +y'(0)sinalpha=0$, $y(pi)coseta+y'(pi)sineta =0$, when $sin alpha eq 0$ and $

Advanced Intelligent Discovery, EarlyView.This article investigates how persistent homology, persistent Laplacians, and persistent commutative algebra reveal complementary geometric, topological, and algebraic invariants or signatures of real‐world data. By analyzing shapes, synthetic complexes, fullerenes, and biomolecules, the article shows how these mathematical frameworks enhance ...

On an eigenvalue problem associated with the (p, q) − Laplacian
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria MatematicaLet Ω ⊂ ℝN, N ≥ 2, be a bounded domain with smooth boundary ∂Ω. Consider the following generalized Robin-Steklov eigenvalue problem associated with the operator 𝒜u = − Δpu − Δqu {𝒜u+ρ1(x)|u|p-2u+ρ2(x)|u|q-2u=λα(x)|u|r-2u, x∈Ω,∂u∂vA+γ1(x)|u|p-2u+γ2(x)|u|

Selective Hydrodemethylation of Methylalkylbenzenes on Potassium Hydride
Angewandte Chemie, EarlyView.Selective catalytic hydrodealkylation of methylalkylbenzenes on carbon‐supported potassium hydride is reported. The reaction exhibits a reactivity trend of 1° ∼ 2° ∼ 3° < CH3, which is opposite to traditional dealkylation and hydrodealkylation. DFT calculations on the (001) facet of KH with ortho‐ethyltoluene suggest that selectivity is controlled by ...
