   111 
   112 \item What knowledge is already mechanised in \emph{isabelle}?
   113 \item How can missing theorems and definitions be mechanised?
   114 \item What is the effort for such mechanisation?
   115 \item How do calculations look like, if using mechanised knowledge?
   116 \item What are the problems and subproblems to be solved?
   117 \item Which problems are already implemented in \sisac?
   118 \item How are the new Problems specified rigorously (\sisac)?
   119 \item Which variantes of programms in \sisac{} solving the problems?
   120 \item What is the contents of the interactiv course material (Figures, etc.)?
