`E` |
The endowment. |

`d` |
The vector of claims. |

`name` |
A logical value. |

Let *E≥ 0* be the endowment to be divided and *d* the vector of claims
with *d≥ 0* and such that the sum of claims exceeds the endowment.

The truncated claim of claimant *i* in *(E,d)* is the minimum of the claim and the endowment.

*ti = min{di,E}, i=1,…,n*

Let *t(E,d)=(t1,…,tn)* be the vector of truncated claims
and *b(E,d)=t(E,d)/n.*

The DT rule is defined recursively such that, in each step, each claimant receives the *n*-th part of the truncated claim.

Let *(E1,δ1)=(E,d)*. For each *k≥ 2* define:

*
(Ek,δk) = ( E(k-1)-∑ bi( E(k-1),δ(k-1) ) , δ(k-1)-b(E(k-1),δ(k-1)) ).*

In step 1, the endowment is E and the claims vector is d.
For *k ≥ 2*, the endowment is the remainder once all the claimants have received the amount of the previous steps and the new vector of claims is readjusted accordingly.
Observe that neither the endowment nor each agent's claim ever increases from one step to the next.
This recursive process exhausts *E* in the limit.

For each *(E,d)* the Dominguez-Thomson rule assigns the awards vector:

*DT(E,d)=∑ b(Ek,δk), where the sum is taken from k=1 to infinity.*

The awards vector selected by the DT rule. If name = TRUE, the name of the function (DT) as a character string.
