Abstract

Fair division with unequal shares is an intensively studied recourse allocation problem. For i[n] i\in [n] , let μi \mu_i be an atomless probability measure on the measurable space (C,S)(C,\mathcal{S}) and let ti t_i be positive numbers (entitlements) with i=1nti=1 \sum_{i=1}^{n}t_i=1 . A fair division is a partition of C C into sets SiS S_i\in \mathcal{S} with μi(Si)ti \mu_i(S_i)\geq t_i for every i[n] i\in [n] . We introduce new algorithms to solve the fair division problem with irrational entitlements. They are based on the classical Last diminisher technique and we believe that they are simpler than the known methods. Then we show that a fair division always exists even for infinitely many players.
