 This thesis is structured as follows

 \section{Introduction}

 todo

 motivation from \textbf{practice of mathematics learning} ... STEOP

 \textbf{mathematics applied} in signal processing (SP)

 mathematics mechanized in Computer Theorem Provers \textbf{(CTP)} ... (almost) traditional mathematical notation (predicate calculus) for axioms, definitions, lemmas, theorems. Recent developments provide also proofs in a humand readable format TODO

 This thesis tries to \textbf{connect these two worlds} ... this trial is one of the first; others see related work

 the major challenge of the practical part is, that ``connecting the two worlds'' involves programming in a CTP-based programming language which is in a very early state of prototyping.

 \subsection{Mechanization of Mathematics}

 todo

 hughe theories of mathematics

 still a hugh gap between these theories and ``real applications'' e.g. in SP

 ? academic engineering starts from physics (experimentation, measurement) and then proceeds to mathematical modelling --- mechanized math starts from mathematical models and (hopefully !) proceeds to match physics.

 CTP Isabelle ... survey of knowledge, links to knowledge

 \paragraph{\sisac}

 TODO

 adds an ``application'' axis (formal specifications of problems) and an ``algorithmic'' axis to the ``deductive'' axis of knowledge ... 3-dimensional universe of mathematics.

 \subsection{Goals of the Thesis}

 \subsection{Milestones for the Project}

 Die Planung des Projekts teilt sich in folgende Iterationen:

 \begin{enumerate}

 \item \textbf{Sammeln von Informationen über Themengebiete und deren Realisierbarkeit } (29.06. -- 27.07.)

 identify problems relevant for certain SP lectures

 estimate chances to realized them within the scope of this thesis

 order for implementing the problems negotiated with lecturers

 \item \textbf{1. Präsentation - Auswählen der realisierbaren Themengebiete} (27.07.)

 \item \textbf{Ausarbeiten der Aufgaben in \isac} (01.09. -- 11.11.)

 \item \textbf{Dokumentation der Aufgaben} (14.11. -- 02.12.)

 \item \textbf{Ausarbeitung in Latex, Bakkarbeit} (05.12. -- todo)

 \item \textbf{2. Präsentation - Abschluss der Arbeit} (todo)

 \end{enumerate}

 \subsection{Structure of the Thesis}

 \section{Mechanization of Mathematics for SP Problems}

 todo

 \subsection{Relevant Knowledge available in Isabelle}

 todo

 \paragraph{example FFT}, describe in detail !!!! 

 ? different meaning: FFT in Maple

 gap between what is available and what is required (@)!

 traditional notation ?

 \subsection{Relevant Knowledge available in \isac}

 todo

 specifications (``application axis'') and methods (``algorithmic axis'')

 partial fractions, cancellation of multivariate rational terms, ...

 \subsection{Survey: Available Knowledge and Selected Problems}

 todo

 estimate gap (@) for each problem (tables)

 conclusion: following order for implementing the problems ...

 \subsection{Formalization of missing knowledge in Isabelle}

 todo

 axiomatization ... where ... and

 \subsection{Notes on Problems with Traditional Notation}

 todo

 u[n] !!

 f x =  why not f(x) ?!?!

 ...

 terms are not full simplified in traditional notations, in isac we have to simplify them complete to check weather results are compatible or not. in e.g. the solutions of an second order linear equation is an rational in isac but in tradition we keep fractions as long as possible and as long as they are 'beautiful' (1/8, 5/16,...)
