Hyperbolic Decay Time Series
Hyperbolic decay time series such as, fractional Gaussian noise (FGN) or fractional autoregressive moving-average (FARMA) process, each exhibit two distinct types of behaviour: strong persistence or antipersistence. Beran (1994) characterized the family of strongly persistent time series. A more general family of hyperbolic decay time series is introduced and its basic properties are characteri...
متن کاملHyperbolic Decay Time Series by A. I. Mcleod
Hyperbolic decay time series such as fractional Gaussian noise or fractional autoregressive moving-average processes exhibit two distinct types of behaviour: strong persistence or antipersistence. Beran (Statistics for Long Memory Processes. London: Chapman and Hall, 1994) characterized the family of strongly persistent time series. A more general family of hyperbolic decay time series is intro...
متن کاملDecay Estimates for Hyperbolic Systems
In this work we study the Sobolev spaces generated by pseudo-differential operators associated with the group of symmetry of general first order hyperbolic systems. In these spaces we establish pointwise estimates of the solutions of a class of first order systems having convex eigenvalues. Various physical models belong to this class. For example, we consider crystal optics systems and anisotr...
متن کاملInverse method for estimating respiration rates from decay time series
Long-term organic matter decomposition experiments typically measure the mass lost from decaying organic matter as a function of time. These experiments can provide information about the dynamics of carbon dioxide input to the atmosphere and controls on natural respiration processes. Decay slows down with time, suggesting that organic matter is composed of components (pools) with varied labilit...
متن کاملRelatively Hyperbolic Groups with Rapid Decay Property
We prove that a finitely generated group G hyperbolic relative to the collection of finitely generated subgroups {H1, . . . , Hm} has the Rapid Decay property if and only if each Hi , i = 1, 2, . . . ,m, has the Rapid Decay property.
