The verbal definition of the sample median sounds a bit strange in early Statistics courses context being non-mathematical or non-functional. It is also interesting that estimators based on an analytical calculation such as mean are equally strange, but not seen by students estimator. In this study, we have expanded studies teaching with its optimization definitions. We shown definitions provid...

A novel inertial inverse-free dynamical system is proposed to solve the absolute value equation (AVE). Under mild conditions, model has a unique solution and its trajectories asymptotically converge of AVE. Compared with existing systems, presence term allows new be more convenient for exploring different solutions Numerical results illustrate effectiveness presented method.

The solid-on-solid model is a of height functions, introduced to study the interface separating $+$ and $-$ phase in Ising model. planar thus corresponds three-dimensional Delocalisation this at high temperature zero slope was first derived by Fr\"ohlich Spencer, parallel proving Berezinskii-Kosterlitz-Thouless transition. main result article consists simple, alternative proof delocalisation In...

Abstract Due to their relation the linear complementarity problem, absolute value equations have been intensively studied recently. In this paper, we present error bound conditions for equations. Along with bounds, introduce a condition number. We consider general scaled matrix p-norms, as well particular p-norms. discuss basic properties of number, including its computational complexity. vario...
