Structural Origin of the Hale Bilinear Form: From the Viewpoint of the Green and Lagrange Identities
Junya Nishiguchi
In the study of linear retarded functional differential equations (RFDEs), the classical bilinear form proposed by J. Hale has long served as an indispensable tool for the geometri…
On regularity of mild solutions for autonomous linear retarded functional differential equations
Junya Nishiguchi
The notion of mild solutions for autonomous linear retarded functional differential equations (RFDEs) has been introduced in [J. Nishiguchi, Electron.\ J. Qual.\ Theory Differ.\ Eq…
Mild solutions, variation of constants formula, and linearized stability for delay differential equations
Junya Nishiguchi
The method and the formula of variation of constants for ordinary differential equations (ODEs) is a fundamental tool to analyze the dynamics of an ODE near an equilibrium. It is n…
Stability region and critical delay
Junya Nishiguchi
The location of roots of the characteristic equation of a linear delay differential equation (DDE) determines the stability of the linear DDE. However, by its transcendency, there…
