Abstract
We define framed curves (or frontals) on Euclidean 2-sphere, give a moving frame of the framed curve and
define a pair of smooth functions as the geodesic curvature of a regular curve. It is quite useful for analysing
curves with singular points. In general, we can not define evolutes at singular points of curves on Euclidean
2-sphere, but we can define evolutes of fronts under some conditions. Moreover, some properties of such
evolutes at singular points are given.
