Introduction A convex cone $V$ in the n-dimensional real number space $R^{n}$ is a non-empty open subset of $R^{n}$ satisfying the following conditions: (1) If $xeV$ and $xeR$ with $\lambda>0$ , then $\lambda x\in V$ . (2) If $x,$ $y\in V$, then $x+y\in V$ . (3) $V$ contains no full straight line. We denote by $G(V)$ the group of all linear automorphisms of $V$, that is, $G(V)=\{A\in GL(n);AV=V\}$ . If the group $G(V)$ acts transitively on $V$, then $V$ is called homogeneous. Let $\langle, \rangle$ be an inner product in $R^{n}$ . Then the dual cone $V^{*}$ of $V$ with respect to the inner product $\langle, \rangle$ is defined by
