Economic theory is an environment where mathematics provides many contributions to model the behavior of economic agents. In this context, this thesis emphasizes the mathematical deployment to deal with the problem of the consumer in an economy described by consumer goods. These form bundles of consumption that are identi ed with elements of a convex cone of an appropriate vector space as is the standard case of Rn, and by a price system, which are identi ed with vectors of the topological dual cone associated with the cone of the bundles of consumption. The problem of the consumer, is a model in which a consumer chooses bundles of goods (which are accessible to him considering his budget constraint) in such a way that maximizes his satisfaction for the consumption of these. The consumer problem can be formulated from two di erent perspectives, either through preferences or through utility functions that represent the agent's satisfaction. In both formulations the solution to the problem of the consumer is a set of bundles of goods giving rise to an application that assigns to each price vector a set of bundles (it can be empty, unitary or of several elements), this application is called correspondence of demand. In the present work a detailed exposition is made of the monotonicity of the correspondence of demand, through preferences and through utility functions, taking into account conditions of di erentiability as well as non-di erentiability with respect to utility functions. In some cases the classic concavity condition for the utility function is weakened. Likewise, the role played by the indirect utility function in the treatment of the monotonicity of the demand function is evident.
