The spatial averaging theorem revisited
WebJun 28, 2024 · The paper gives a comprehensive study of inertial manifolds for semilinear parabolic equations and their smoothness using the spatial averaging method suggested by G. Sell and J. Mallet-Paret. We present a universal approach which covers the most part of known results obtained via this method as well as gives a number of new ones. Among … WebThe weights used in spatial averaging do not have to be uniform, even if observations themselves are uniformly spaced, but can differ according to the goal of the inquiry (Vinnikov et al.

The question is whether we need to worry about these variations or can we find some way to "absorb" or "average" them away. Most instrumentation will unintentionally "average" out …
WebThe averaging theorem. The averaging theorem used is due to Slattery (1967) and is based on the idea that volume averages of derivatives are closely related to derivatives of volume averages, but care must be taken to account properly for behavior of the averaged quantities at points or surfaces where abrupt changes occur.
