Set theory is a branch of mathematics created principally by the German mathematician Georg Cantor at the end of the 19th century.
Shelah also solved several outstanding questions from other fields, among them: In mathematics, model theory is the study of the representation of mathematical concepts in terms of set theory, or the study of the models which underlie mathematical systems.
PCF theory is the name of a mathematical theory, invented by Saharon Shelah, that deals with power sets of singular cardinals.

 Shelah receives Bolyai prize   (Site not responding. Last check: 2007-11-06)
Saharon Shelah (Hebrew University, Jerusalem, Israel and Rutgers University, New Jersey) has been awarded the János Bolyai International Mathematical Prize of the Hungarian Academy of Sciences, which consists of a medal and an award of $25,000.
This award was established in 1903 by the Hungarian Academy of Sciences in honor of János Bolyai, co-discoverer of non-Euclidean geometry, and was presented to H. Poincaré in 1905 and to D. Hilbert in 1910, after which various historical events, beginning with the first World War, forced its interruption.
His solutions to deep and longstanding problems and his independence techniques forever changed the landscape of set theory; this is even more true in model theory where his concepts and methods have completely revolutionized the area.

While Shelah successfully argues paramatric indices approaching various asymptopals, he fails to create a cogent argument for connecting classical arithmetic and fractions to the subtleties of salubrious varistor scanning and its application to the classification of supine numerical systems.
Shelah's book is probably one of the most original publication in the history of modern mathematics.
Shelah's approach to the area is influenced by the discovery of set theory and Paul Erdos's work in combinatorics.

Shelah's categoricity conjecture: If an L_{\omega_1,\omega} theory is categorical in a cardinal greater than the Hanf number then the theory is categorical in every cardinal above the Hanf number.
In the late seventies Shelah introduced the notion of abstract elementary class (a semantic generalization of L_{\omega_1,\omega} theory) and formulated a similar strong categoricity conjecture.
Recently Monica VanDieren and the speaker proved that Shelah's conjecture holds for a large family of abstract elementary classes.

Normed forcing first established its usefulness in Saharon Shelah's seminal proof that the splitting number can be greater than the unboundedness number.
The essential idea was to use measures (often on finite sets) to control the splitting nodes of trees used as forcing conditions.
Lately, in more joint work with A. Roslanowski, a simple form of integration was added to the mix and has allowed the solution of several longstanding problems in the theory of measurable functions.
