The one which has worked several publications about the same under Peruvian law, which incidentally part of the Peruvian doctrine, which is a source of law. I.e., suggest the inquiry of his research work, which explains all almost modern contracts, however, this is not done with some modern as e.g. with the companies lease contracts, which is true it is a contract, it is also true that it is little diffusion in Peruvian law and also of course little application in the same. 12 Groups of companies of enterprises groups are sets of companies and are assumptions of business concentration, in which there are two types or kinds of concentration which are as follows: groups of companies in relation of subordination and groups of companies in relation of coordination.
