چکیده
in the present paper an operator-differential equation of second order in complex domain isconsidered when the coefficients have singularity of pole type at the point z=0. a theorem of existence of thesolution of the equation is proved and the spectral property of the solution is separately investigated when thecoefficients are spectral operators.

Some Remarks on the Solvability of Some Abstract Differential Equations
This paper is concerned with the solvability of some abstract differential equation of type u̇(t) + Au(t) + Bu(t) ∋ f(t), t ∈ (0, T ], u(0) = 0, where A is a linear selfadjoint operator and B is a nonlinear (possibly multi-valued) maximal monotone operator in a real Hilbert space H with the normalization 0 ∈ B(0). We use the concept of variational sum introduced by H. Attouch, J.-B. Baillon, and...

On the Solvability of Magnetic Differential Equations
The calculation of both resistive and ideal plasma equilibria amounts to solving a number of magnetic differential equations which are of the type ~ B ·∇Φ = s. We apply the necessary and sufficient criterion for the existence of the potential Φ and find that a static equilibrium configuration of a magnetically confined plasma does not exist in axi-symmetric toroidal geometry. AMS classification...

In this study, a new and efficient approach is presented for numerical solution of Fredholm integro-differential equations (FIDEs) of the second kind on unbounded domain with degenerate kernel based on operational matrices with respect to generalized Laguerre polynomials(GLPs). Properties of these polynomials and operational matrices of integration, differentiation are introduced and are ultili...
