It is important to study the propagation and interaction of progressing waves of nonlinear equations in the class of piecewise smooth function. However, there h
In this paper, the problem of decentralized observation and decentralized control of linear, time-invariant large scale systems is studied. Based on conventiona
In this paper, we study the computative Structure of computable function——a structure of computative tree, and, by analysis on it, got the most general algori
In this paper, we discuss the limit cycles of the systemdx/dt=y·[1+(A(x)]oy/dt=(-x+δy+α<sub>1</sub>x<sup>2</sup>+α<sub>2</sub>xy+α<sub>5</sub>x<sup>2</sup
