Additive rules in bankruptcy problems and other related problems

In this paper we characterize the set of rules satisfying additivity on the estate along with additivity on the estate and the claims in bankruptcy problems and other related problems. Moreover, new characterizations of the well known rules based on the principles of “equal award”, “equal loss”, and “proportionality” are provided using these additivity properties.

Daisies and Other Turán Problems

Our aim in this note is to make some conjectures about extremal densities of daisy-free families, where a ‘daisy’ is a certain hypergraph. These questions turn out to be related to some Turán problems in the hypercube, but they are also natural in their own right. We start by giving the daisy conjectures, and some related problems, and shall then go on to describe the connection with vertex-Tur...

AUozyme differentiation and relationship among the Iberian-Pyrenean Mountain Lizards

Six nominal taxa ('Lacerta' monticola cantabrica, 'L. ' monücola monticola, 'L. ' aranica, 'L. ' aurelioi, 'L. ' bonnali, 'L. ' cyreni) of the Iberian-Pyrenean Mountain Lizards were investigated by allozyme electrophoresis with regard to IS enzymatic loci. 'L. ' horvathi was used as an outgroup for phylogenetic analysis. On the basts of our results which are in perfect agreement with karyologic...
