标题： Uncertainty of Velocity in kappa-Minkowski Spacetime

摘要： 点粒子在kappa-Minkowski时空中的速度被研究。 时空的特征是Poincare群成为一个量子群，其中kappa是一个质量维度参数，并且是一种非对易几何。 我们考虑粒子在坐标空间中的情况，而不是许多文章中讨论的动量空间中的粒子。 我们发现粒子的速度存在不确定性，该不确定性取决于粒子传播的长度。 显示英文摘要

摘要： A velocity of a point particle in the kappa-Minkowski spacetime is investigated. Characteristic points of the spacetime are that the Poincare group becomes a quantum group with kappa, which is a mass dimension parameter, and is a kind of non-commutative geometry. We consider a particle in a coordinate space instead of it in a momentum space which is discussed in many articles. We see that the particle's velocity has an uncertainty which depends on a length of particle's propagation.
