Vor einem Tag · Central limit theorem. In probability theory, the central limit theorem ( CLT) states that, under appropriate conditions, the distribution of a normalized version of the sample mean converges to a standard normal distribution. This holds even if the original variables themselves are not normally distributed.
Vor 45 Minuten · Abstract. We construct examples of smooth periodic solutions to the Magnetohydrodynamic equations in dimension 2 with positive resistivity for which the topology of the magnetic lines changes under the flow. By Alfvén’s theorem this is known to be impossible in the ideal case (resistivity \ (=\) 0). In the resistive case the reconnection of ...
