The Algebraic Multiplicity of Eigenvalues and the Evans Function Revisited
Y. Latushkin, A. Sukhtayev (2010)
Mathematical Modelling of Natural Phenomena
This paper is related to the spectral stability of traveling wave solutions of partial differential equations. In the first part of the paper we use the Gohberg-Rouche Theorem to prove equality of the algebraic multiplicity of an isolated eigenvalue of an abstract operator on a Hilbert space, and the algebraic multiplicity of the eigenvalue of the corresponding Birman-Schwinger type operator pencil. In the second part of the paper we apply this result...

The existence of bounded solutions for differential equations in Hilbert spaces
B. Przeradzki (1992)
Annales Polonici Mathematici
The existence of bounded solutions for equations x' = A(t)x + r(x,t) is proved, where the linear part is exponentially dichotomic and the nonlinear term r satisfies some weak conditions.

The General Differential Operators Generated by a Quasi-Differential Expressions with their Interior Singular Points
El-sayed Ibrahim, Sobhy (1999)
Serdica Mathematical Journal
The general ordinary quasi-differential expression M of n-th order with complex coefficients and its formal adjoint M + are considered over a regoin (a, b) on the real line, −∞ ≤ a < b ≤ ∞, on which the operator may have a finite number of singular points. By considering M over various subintervals on which singularities occur only at the ends, restrictions of the maximal operator generated by M in L2|w (a, b) which are regularly solvable with respect to the minimal operators T0 (M ) and T0...
