The fractional cable equation is studied on a bounded space domain. One of the prescribed boundary conditions is of Dirichlet type, the other is of a general form, which includes the case of nonlocal boundary conditions. In real problems nonlocal boundary conditions are prescribed when the data on the boundary can not be measured directly. We apply spectral… (More)

The one-dimensional Dunkl operator D k with a non-negative parameter k, is considered under an arbitrary nonlocal boundary value condition. The right inverse operator of D k , satisfying this condition is studied. An operational calculus of Mikusi´nski type is developed. In the frames of this operational calculi an extension of the Heaviside algorithm for… (More)

Short review of an approach to explicit solving of initial and boundary value problems (BVPs) for some partial differential equations (PDEs) is presented. A combination of two classical methods Å the Fourier method and the Duhamel principle Å is used in the framework of a two-dimensional operational calculus. It gives explicit solutions of some local and… (More)

A review of our operational calculus approach to obtaining periodic and mean-periodic solutions of LODE with constant coefficients is presented. Let P (λ) = a 0 λ n + a 1 λ n−1 + · · · + a n−1 λ + a n be a non-zero polynomial with constant coefficients of degree n and let us consider an ordinary linear differential equation of the form: P d dt y = f (t), −∞… (More)

The theory of the nonlocal linear boundary value problems is still on the level of examples. Any attempt to encompass them by a unified scheme sticks upon the lack of general methods. Here we are to outline an algebraic approach to linear nonlocal boundary value problems. It is based on the notion of convolution of linear operator and on operational… (More)

The Pommiez operator (∆ f)(z) = (f (z) − f (0))/z is considered in the space Ᏼ(G) of the holomorphic functions in an arbitrary finite Runge domain G. A new proof of a representation formula of Linchuk of the commutant of ∆ in Ᏼ(G) is given. The main result is a representation formula of the commutant of the Pommiez operator in an arbitrary invariant… (More)
