Decomposition of Additive Random Fields

Vestnik St. Petersburg University, Mathematics, 2020
The authors study additive random fields \[ Y_d(t)= \sum_{j=1}^dX_j(t_j),\ t=(t_1,\ldots,t_d)\in [0,1]^d, \] where \(X_j(t_j), j=1,\ldots,d,\) are uncorrelated random processes with zero mean and the same continuous covariance function. The case when all eigenvalues of the covariance operator of the marginal processes equal 1 is rather simple for ...

Additive Decomposition of Finite Processes

IFAC Proceedings Volumes, 1986
Abstract In various branches of the random process analysis it is a common practice to split measured signals into trend and stochastic components (Anderson, 1971; Bendat, 1980). This is invariably the case, when performing identification, prediction and spectrum evaluation.

Additive decomposition of ideals

Journal of Algebra and Its Applications, 2018
In this paper, we investigate decomposition of (one-sided) ideals of a unital ring [Formula: see text] as a sum of two (one-sided) ideals, each being idempotent, nil, nilpotent, T-nilpotent, or a direct summand of [Formula: see text]. Among other characterizations, we prove that in a polynomial identity ring every (one-sided) ideal is a sum of a nil ...

Additions to the Periodic Decomposition Theorem

Acta Mathematica Hungarica, 2001
An \(n\)-tuple \((T_1,\dots,T_n)\) of commuting (linear, bounded) operators on a Banach space \(X\) has the decomposition property if \[ \ker((I-T_1)\dots(I-T_n))\subset\ker(I-T_1)+\dots+\ker(I-T_n). \] An operator \(T\) is power bounded if \(\sup\{\|T^k\|\colon k\in{\mathbb N}\}\) is finite. A Banach space \(X\) has the \(n\)-decomposition property if
