Competitive equilibria in economies with multiple indivisible and multiple divisible commodities

In the model to be presented in this paper we consider an economy without production and with multiple divisible and multiple indivisible commodities. Convexity is replaced by pseudoconvexity, while the indivisible parts of individual demands should belong to some class of discrete convexity. One of the divisible commodities serves as money. Money is strictly desired by all consumers and there should be enough money present in the economy. To guarantee existence of a general equilibrium individual demands should be products of divisible and indivisible parts. In case there is no money, at least one linear production technology besides possibly other producers should be present in order to produce divisible goods.
