Transmission conditions for the Helmholtzequation in perforated domains [PDF]
, 2015 We study the Helmholtz equation in a perforated domain . The domain Ωε. The domain Ωε is obtained from an open set Ω⊂ℝ³ by removing small obstacles of typical size ε > 0, the obstacles are located along a 2-dimensional manifold Γ0 ⊂Ω, We derive ...

Bifurcation for some quasilinear operators [PDF]
, 2001 This paper deals with existence, uniqueness and multiplicity results of positive solutions for the quasilinear elliptic boundary-value problem $$\begin{array}{c} -\mbox{div}\, (A(x,u)\nabla u) = f(\lambda,x, u), \quad \mbox{ in } \Omega , \\u = 0 ...

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Schrödinger equations in noncylindrical domains: exact controllability
International Journal of Mathematics and Mathematical Sciences, 2006 We consider an open bounded set Ω⊂ℝn and a family {K(t)}t≥0 of orthogonal matrices of ℝn. Set Ωt={x∈ℝn;x=K(t)y,for all y∈Ω}, whose boundary is Γt.
