1. On the tangential velocity arising in a crystalline approximation of evolving plane curves Creator: Yazaki, Shigetoshi Format: bez média and svazek Type: model:article and TEXT Subject: tangential velocity, intrinsic heat equation, crystalline algorithm, and admissible polygonal curve Language: English Description: In a crystalline algorithm, a tangential velocity is used implicitly. In this short note, it is specified for the case of evolving plane curves, and is characterized by using the intrinsic heat equation.
