| Jun 20, 2020 at 12:49 | comment | added | Jochen Glueck | Thank you very much for your response! Hmm, may I suggest to include a definition of your usage of the word cone in the question? (I just browsed half a dozen books about ordered vector spaces; many of them define a cone indeed to be always convex, while some others do not - and there also seem to be some further differences between the various definitions of a cone in the literature). | |

| Jun 19, 2020 at 21:27 | comment | added | Jochen Glueck | I assume that $\operatorname{Conv} A$ denotes the convex hull of $A$? But why do you need to take the convex hull of a cone, given that a cone is already convex? | |
