We compare two prominent approaches to capital allocation in insurance firms. The financial theory approach includes Merton and Perold (1993) and Myers and Read (2001). The cooperative game theory approach utilizes concepts such as the Shapley value and the Aumann-Shapley value. We argue that,...

The magnetic properties of a decorated Ising system with a random field at the decorated atom are investigated by the use of the effective-field theory with correlations. In particular, the phase diagram and magnetization curve of the decorated ferrimagnetic honeycomb lattice are examined...

The phase diagrams of the semi-infinite Ising ferromagnet with decorated magnetic (spin-S) and nonmagnetic atoms on the surface are investigated within the framework of the effective-field theory. In particular, the critical properties of the special point in the surface phase diagram are...
