Pierre-Nol Giraud seala el fenmeno de la desigualdad como punto fundamental en los estudios econmicos. El examen de la doble dimensin -espacial y social- del problema ayuda a Giraud a establecer los fundamentos para una revisin profunda de las teoras econmicas existentes.

Of all the different areas in computational chemistry, density functional theory (DFT) enjoys the most rapid development. Even at the level of the local density approximation (LDA), which is computationally less demanding, DFT can usually provide better answers than Hartree-Fock formalism for large systems such as clusters and solids. For atoms and molecules, the results from DFT often rival those obtained by ab initio quantum chemistry, partly because larger basis sets can be used. Such encouraging results have in turn stimulated workers to further investigate the formal theory as well as...

La finalidad de este libro es concentrar en un espacio mínimo, una importante porción de los fundamentos esenciales de la moderna Cinética química. El estudio de la mayor parte de los temas, en consecuencia, es breve, aunque razonablemente riguroso, algunas veces incompleto, pero raramente superficial.

The section devoted to iron in this volume reflects the tremendous progress in the area. Specifically cluster chemistry, ligand transformations and detailed structural results are more prominent in COMC II. The organic chemistry of ruthenium and osmium is an area which has burgeoned during the period since the publication of COMC. This is especially true for the cluster chemistry of these elements, which have provided most of the advances in this important field. Consequently, this volume will include an update (1981-1993) of the chemistry of mono- and bi-nuclear complexes of ruthenium and...
