We prove the existence of solutions to the differential inclusion ẍ(t) ∈ F (x(t), ẋ(t)) + f(t, x(t), ẋ(t)), x(0) = x0, ẋ(0) = y0, where f is a Carathéodory function and F with nonconvex values in a Hilbert space such that F (x, y) ⊂ γ(∂g(y)), with g a regular locally Lipschitz function and γ a linear operator.

We consider an inverse scattering problem and its near-field approximation at high frequencies. We first prove, for both problems, Lipschitz stability results for determining the low-frequency component of the potential. Then we show that, in the case of a radial potential supported sufficiently near the boundary, infinite resolution can be achieved from measurements of the near-field operator ...

 In this paper, we introduce new classes $sum_{k,p,n}(alpha ,m,lambda ,l,rho )$ and $mathcal{T}_{k,p,n}(alpha ,m,lambda ,l,rho )$ of p-valent meromorphic functions defined by using the extended multiplier transformation operator. We use a strong convolution technique and derive inclusion results. A radius problem and some other interesting properties of these classes are discussed.

Using a generalized translation operator, we obtain a generalization of Theorem 5 in [4] for the Bessel transform for functions satisfying the (delta;gamma ; 2)-BesselLipschitz condition in L_{2;alpha}(R+).  

In a previous paper by Birman and Filonov, the spectrum of the Maxwell operator with nonsmooth coefficients in Lipschitz domains was investigated. The claim that its eigenvalues obey the Weyl asymptotics was proved up to a statement about the spectrum of an auxiliary problem with constraint. The proof of that statement is given in the present paper. §

Let L be a second order, (variable coefficient) elliptic differential operator and let u ∈ Bp,p α (Ω), 1 < p < ∞, α > 0, satisfy Lu = 0 in the Lipschitz domain Ω. We show that u can exhibit more regularity on Besov scales for which smoothness is measured in Lτ with τ < p. Similar results are valid for functions representable in terms of layer potentials.

The aim of this work is to use resolvent operator technique to find the common solutions for a system of generalized nonlinear relaxed cocoercive mixed variational inequalities and fixed point problems for Lipschitz mappings in Hilbert spaces. The results obtained in this work may be viewed as an extension, refinement and improvement of the previously known results.

We study the invertibility of λI+K in Lp(∂Ω×R), for p near 2 and λ ∈ R, |λ| ≥ 12 , where K is the caloric double layer potential operator, and Ω is a Lipschitz domain. Applications to transmission boundary value problems are also presented.

Let C(R) be the space of functions on R whose m derivatives are Lipschitz 1. For E ⊂ R, let C(E) be the space of all restrictions to E of functions in C(R). We show that there exists a bounded linear operator T : C(E)→ C(R) such that, for any f ∈ C(E), we have Tf = f on E.
