โฆ Synopsis
It is well known that successive overrelaxation (SOR) can be used to compute the stationary distribution of a homogeneous Markov chain. In a long paper Kontovasalis et al. (K. Kontovasalis, R.J. Plemmons, W.J. Stewart, Linear Algebra Appl. 154-156 (1991) showed together with other results that for p-periodic Markov chains convergence of SOR in an extended sense can happen for m ยข (0, 2). The purpose of this note is to show how this astonishing result can be derived comparatively easy for twoperiodic Markov chains from the well-known convergence properties of power iteration.

## Abstract A new procedure to model extended cortical sources from EEG and MEG recordings based on a probabilistic approach is presented. The method (SPMECS) was implemented within the framework of maximum likelihood estimators. Neuronal activity generating EEG or MEG signals was characterized by
In this note, we provide answers to two hitherto unstudied questions in the tourism literature. Specifi cally, we fi rst show how the theory of discrete-time Markov Chains (DTMCs) can be used to effectively model and analyze the problem of providing guided tours to tourists during the off-peak seaso
