In establishing of basis properties of the system (4) in (L_{p cdot),rho} ), we will apply the method of boundary value problems, namely, we will consider the following Riemann problem: left { textstylebegin{array}{l} F^ (tau )+e^{-2igamma(t)} F^ (tau )=g (tau )e^{-igamma(t)}, F^ in H_{p cdot),rho}^, qquad F^ in_{-1} H_{p cdot),rho}^, end{array}displaystyle right.
In this paper, the boundary element method is applied in order to find an improved numerical solution for a boundary value problem with a nonlinear boundary condition, namely the two-dimensional problem of the compressible fluid flow around obstacles.
Proof Because of the linearity of the problem defined by (8), (6) and (7), we deduce that the differences ( v i, χ ) represent the solution of a mixed initial boundary value problem analogous to (8), (6) and (7), namely the problem consisting of equations (12) and (13) with loads F i, respectively P, the initial conditions (14) and boundary conditions (15).
In this section we investigate a nonlinear elliptic partial differential equation, namely the nonlinear boundary value problem: { − Δ u = f ( | u | ) sgn u in Ω, u = 0 on ∂ Ω. (25) Here we assume that f is the derivative of a Hölder function α satisfying a slope condition; f : = α ′.
We consider critical points of the Trudinger Moser type functional Jλ u)= 12∫Ω|∇u|2−λ2∫Ωeu2 in H10, namely solutions of the boundary value problem Δu+λueu2="0 with homogeneous Dirichlet boundary conditions, where λ>0 is a small parameter.
Compared with previous papers involving impulsive fractional order differential equations, the impulse of our boundary value problem (1.1) is related to the fractional order derivative, namely, (Delta D^{alpha-1}u(t_{k})= I_{k} u(t_{k}))).
The spectrum of the transformed boundary value problem (3.3), (3.9) is the same as that of (2.5), (2.14) except for one additional eigenvalue, namely,.
Thus this boundary value problem in has the same spectrum as that of (3.3), (3.9) but with one eigenvalue removed, namely,.
