Resumo: | This paper deals with the problem of the existence of solid hulls for concrete categories. Sufficient conditions are given for the existence of a solid hull of a concrete category. For concrete categories over Set with a small finally dense subcategory, we show that the existence of solid hulls is equivalent to Weak Vopenka's Principle. |

This paper deals with the problem of the existence of solid hulls for concrete categories. Sufficient conditions are given for the existence of a solid hull of a concrete category. For concrete categories over Set with a small finally dense subcategory, we show that the existence of solid hulls is equivalent to Weak Vopenka's Principle. |
