    Some Properties of a Class of Wiener Difference Processes and Wavelet Express

    Get PDF
    Recently, some researchers have studied wavelet problems of stochastic processes or stochastic system by using wavelet. In this paper, we take wavelet and use it in a series expansion of signals or functions. Wavelet has its energy concentration in time to give a tool for the analysis of transient and nonstationary and time-varying phenomena. Wavelets have contributed to this already intensely developed and rapidly advancing field. The study of Wiener difference processes stochastic system is very important in theory and application. In this paper, Wiener difference processes are studied by using wavelet analysis, and some properties and wavelet express are obtained

    Spectral Properties and Finite Pole Assignment of Linear Neutral Systems in Banach Spaces

    Get PDF
    We will consider a pole assignment problem for a class of linear neutral functional differential equations in Banach spaces. We will think of the neutral system studied as that of involving no time delays and reduce the study of adjoint semigroups and spectral properties of neutral equations to those of Cauchy problems. Under the assumption that both the control and eigenspace of pole are finite dimensional, we establish the rank conditions for finite pole assignability
