On algebraic \(\sharp\)-cones in topological tensor algebras. II: Closed hulls and extremal rays
The author continues the study of alg-\# cones \(\{F,\#\}\) in topological tensor algebras started in [Publ. Res. Inst. Math. Sci. 28, No. 3, 455-494 (1992; Zbl 0808.46079)]. It is proved that the elements of the closed hulls of some alg-\# cones are given by sums of elements of \(\{F,\#\}\). Also, a (cone) Krein-Milman type theorem is presented for a class of alg-\# cones in terms of extremal rays.
