The hydrogen abstraction reaction of OH radical with CH3CH2OCF2CHF2 (HFE-374pc2) is investigated theoretically by semi-classical transition state theory. The stationary points on the potential energy surface of the reaction are located by using KMLYP density functional method along with 6-311++G(d,p) basis set. Vibrational anharmonicity coefficients, ...

We construct an invariant deformation retract of a deformation space of G–trees. We show that this complex is finite dimensional in certain cases and provide an example that is not finite dimensional. Using this complex we compute the automorphism group of the classical non-solvable Baumslag–Solitar groups BS(p, q). The most interesting case is when p properly divides q. Collins and Levin compu...

In this paper we study a class of double phase problems involving critical growth, namely−div(|∇u|p−2∇u+μ(x)|∇u|q−2∇u)=λ|u|ϑ−2u+|u|p⁎−2uin Ω,u=0on ∂Ω, where Ω⊂RN is bounded Lipschitz domain, 1<ϑ0, respectively. Based on variational topol...

Abstract We consider a nonlinear Dirichlet problem driven by the ( p , q )-Laplacian and with reaction having combined effects of singular term parametric $$(p-1)$$ (p-1) -superlinear perturbation. prove bifurcation-type re...
