1.169 -%Hab noch keine Ahnung, was ich da rein schreiben soll, aber alles wird gut :) HOFFENTLICH!!!!!!\\
1.170 -%Allgemeine Einleitun?
1.171 +Calculation with fractions is an importent part of Computer-Algebra-Systems (CAS). Therefor you need algorithms for canceling fractions, respectively for the greatest common divisor (GCD).
1.172 \section{Background}
1.173 -%Warum ich diese Arbeit schreibe?
1.174 +The ISAC-project is a research and development project at the Institute for Software Technology of the Graz University of Technology. ISAC is an educational mathematics assistant, a single-stepping system for applied mathematics based on the computer theorem prover Isabelle. The novelty is given by the human-readable knowledge base including Isabelles HOL-theories and by the transparently working knowledge interpreter (a generalization of 'single stepping' algebra systems). The background to both, development and research, is given by actual needs in math education as well as by foundamental questions about 'the mechanization of thinking' as an essential aspect in mathematics and in technology. The ISAC-system under construction comprises a tutoring-system and an authoring-system. The latter provides for adaption to various needs of individual users and educational institutions and for extensions to arbitrary fields of applied mathematics.

1.176 \section{Goal of the thesis}
1.177 \subsection{Current situation}
1.178 -%Lernsystem, das Wert auf "`Durchsichtigkeit"' legt.
1.179 +Zur Zeit ist keine gute Implimentierung vorhanden. Um polynomiale Brüche zu kürzen, darum besteht die Notwendigkeit eienr Implimentierung in Isabelle, auf die von Isac zugegriffen wird.
1.180 \subsection{Problem}
1.181 -%Das Kürzen von Multivariablen Polynomen ist noch nicht zufriedenstellend implimentiert.
1.182 +
1.183 +In Isac möchte man gerne Brüche kürzen können und dies nicht nur mit einer Variablel sondern auch mit mehrern Variablen. So the goal of this thesis ist to find, assess and evaluate the existing algorithms and methods for finding the GCD. This will be an functional programm with the posibility to include it in Isabelle.
1.184 \subsection{Expected results}
1.185 -%richtige implimentierung in isac basierend auf Isabelle.\\
1.186 -%Funktional programmiert und Schrittweise nach zu voll ziehren.\\
1.187 -%Funktonen: Was wurde gemacht, Schrittweise auswählen, was man zuerst machen will, falls es mehrer Möglichkeiten gibt.(zumindest bei Univariaten Polynomen)
1.188 +Polynome kürzen und addieren ( wenn sie in Normalform sind)\\
1.189 +Für reale koeffizienten eventuell auch für imaginäre oder rationale.\\
1.190 +richtige implimentierung in isac basierend auf Isabelle.\\
1.191 +Funktional programmiert mit guten Beschreibungen, was gerade gemacht wird.\\

1.194 \section{State of the art}
1.195 -%Was ist vorhanden, was kann ich aus welchen Büchern für meine Arbeit verwenden?
1.196 -%SCHEI?E; das weiß ich doch nicht GGGRRRRR hätt wohl doch früher anfangen sollen. :(
1.197 +Was ist vorhanden, was kann ich aus welchen Büchern für meine Arbeit verwenden
1.198 +Es gibt verschiedene CAS die bereits einen Algrotihmus implimentiert haben, wie haben die das gemacht, und welcher ist für mich am besten.
