摘要:

AbstractThe notion of a pre‐Nevanlinna matrix of entire functions is introduced, and we find necessary and sufficient conditions for an entire function to belong to such a matrix, thereby generalizing previous work of Krein.If one of the functions in a pre‐Nevanlinna matrix is a polynomial, then the three others arc also polynomials and their degrees differ by at most two. If the functions in a pre‐Nevanlinna matrix are transcendental they have necessarily the same order, type and indic

摘要:

AbstractWe use perturbation methods based on inverse scattering transform to study the dynamical behavior of the kink‐antikink solitons exhibited by a driven‐damped sine‐Gordon equation with infinite boundary condition. It is shown that such solitons may be forced by damping and external forces to remain in a finite region instead of approaching inf

摘要:

AbstractAn indefinite trigonometric moment problem is solved using the one‐step completion and the geometry involved in extending factorizations in Kreîn spaces. In addition, a description of all the solutions is obtained as well as a simple characterization of the case when there exists exactly one solution of the probl

摘要:

AbstractThe aim of this paper is to deduce oscillatory and asymptotic behaviour of delay differential equationLnu(t)– P(t)u(τ(t))= 0 from the oscillation of a set of the first order delay differential equations with larger deviating argument of the formy′(t)+ qi(t) y(w(t))

摘要:

AbstractA number of operator inclusions, and identities, involving the Moore‐Penrose inverse of a closed densely defined linear operator, are presented. Some of these inclusions generalize known identities in the case when the operator is bounded and has closed range. An application to a known compactness criterion for the Moore‐Penrose inverse is also gi
