In this paper, we establish several sufficient conditions for a compact spacelike surface with non-degenerate second fundamental form in the 3-dimensional de Sitter space to be spherical. With this aim, we develop a formula for these surfaces which involves the mean and Gaussian curvatures of the fi

In this paper, we consider coherent imprecise probability assessments on ยฎnite families of conditional events and we study the problem of their extension. With this aim, we adopt a generalized deยฎnition of coherence, called g-coherence, which is based on a suitable generalization of the coherence pr
