This paper considers the estimation problem of a variance change-point in linear process. Consistency of a SCUSUM type change-point estimator is proved and its
For maximal multilinear Calderón-Zygmund singular integral operators, the sharp maximal function estimate and some weighted norm inequalities are obtained.
We have developed a path integral formalism of the quantum mechanics in the rotating frame of reference, and proposed a path integral description of spin degree
Time-domain state-domain methods are common approaches in modern financial analysis. Economic conditions vary time, drift function depends on time and price lev
