Existence of fixed point in orthogonal metric spaces has been initiated recently by Eshaghi and et al. [On orthogonal sets and Banach fixed Point theorem, Fixed Point Theory, in press]. In this paper, we introduce the notion of the strongly orthogonal sets and prove a genuine generalization of Banach' fixed point theorem and Walter's theorem. Also, we give an example showing that our main theor...

• Net income was Ps. 1.903 billion (including monetary gains of Ps. 1.039 billion), or US$245 million, during the third quarter of 1997.

Over the entire course of the debate, Block (1977, 1995, 2000) has argued that when individuals have only psychic income with which to maintain their property rights, the Coase theorem fails. A...
