The generalized Langevin equation (GLE) is used widely in molecular science and time series analysis as it offers a convenient low-dimensional description for large systems. There the dynamical effect of environment interacting with system expressed friction random force. present paper aims to investigate explicit variables describe modes that are derived from GLE defined solely terms observed variable. formulation results equations motion without memory term hence more intuitive than GLE. framework provided by study expected elucidate multi-dimensional dynamics hidden behind quantity.
