Averaging Theory for Fractional Differential Equations

Fractional Calculus and Applied Analysis, 2021
The theory of averaging is a classical component of applied mathematics and has been applied to solve some engineering problems, such as in the filed of control engineering. In this paper, we develop a theory of averaging on both finite and infinite time

Theory of synchronous averaging

2004 IEEE Aerospace Conference Proceedings (IEEE Cat. No.04TH8720), 2004
Synchronous averaging is commonly known as time synchronous averaging (TSA) but is applicable to many independent variable domains that demonstrate periodic signals of interest. An alternative domain of example is the spatial domain. The common use of the synchronous averaging technique is the attenuation of both non-coherent components and the non ...

On the theory of average case complexity

Proceedings of the twenty-first annual ACM symposium on Theory of computing - STOC '89, 1989
This paper takes the next step in developing the theory of average case complexity initiated by Leonid A. Levin. Previous works [Levin 84, Gurevich 87, Venkatesan and Levin 88] have focused on the existence of complete problems. We widen the scope to other basic questions in computational complexity.

The Theory of Averaging

1985
This chapter will be concerned with the theory of averaging for equations in the standard form $$\dot x = \in f\left( {t,x} \right) + { \in ^2}R\left( {t,xm \in } \right)$$

Gravitation as an averaged theory

International Journal of Theoretical Physics, 1984
A result due to Eisenhart is used to justify an averaging process of a theory of gravity. More results of the theory are also deduced, similar to those derived by Einstein for the Nordstrom theory.
