Before revision:  In summary, TA and the\textit{  Spherical-CHM provide a convenient geometric setting for efficient solution to large-scale CHM and related problems, such as computing all vertices of conv(S)\emph{ }\hspace{0pt}%DIFAUXCMD , called }\emph{ }\hspace{0pt}%DIFAUXCMD } .
After revision:  In summary, TA and the\textit{ Spherical-CHM before applying the algorithm. Next we introduce a series of applications of Spherical-TA. In particular, Spherical-TA serves as a fast version of vanilla TA to boost its efficiency. As an example, this results in a fast version of\emph{ }\hspace{0pt}%DIFAUXCMD , called }\emph{ }\hspace{0pt}%DIFAUXCMD } .
