Our concern is iterative solvers for these systems and a quality of approximate solutions. This quality depends on stability properties of the Galerkin method. Possible ways of enhancing the stability are discussed. Analysis and Biomathematics Seminar. We monitor the activity of neurons while subjects direct gaze to visual stimuli.
Some neurons contribute to selecting the target for a movement of the eyes.
Other neurons contribute to producing the movement of the eyes. The purpose of this talk is to introduce the kind of data we collect, the analyses we perform and the open questions. For example, it is well known that large populations of neurons are necessary to carry out these functions. However, paradoxically, we have found that the signals produced by very few neurons are sufficient to account for the performance. We will start with a characterization of the algebras that are isomorphic to the factor of a subdirectly irreducible algebra by its monolith.
