(Real) Vectors in Euclidean space, and elementary linear algebra.

A generic decision procedure for linear rea arithmetic and normed vector spaces

Permutations, both general and specifically on finite sets.

Imports Main in order to avoid the typerep problem

A theory of greatest lower bounds

Now imports Fact as suggested by Florian in order to avoid the typerep problem

Added HOL/Library/Finite_Cartesian_Product.thy to Library

A formalization of finite cartesian product types

Proof method 'reify' is now reentrant.

added noatps

check for destination directory, do not allocate it gratuitously

Isar proof

merged

code theorems for nth, list_update

added bulkload

added bulkload

added Decision_Procs.thy

merged

session Reflecion renamed to Decision_Procs, moved Dense_Linear_Order there

authentic syntax for List.nth

Merged.

Rearrange Refute/SAT theory dependencies so as to use even more antiquotations in refute.ML + find/fix Product_Type.{fst,snd}, which are now called simply fst and snd.

Automated merge with ssh://chaieb@atbroy100.informatik.tu-muenchen.de//home/isabelle-repository/repos/isabelle

fixed import

Add approximation method

Added new Float theory and moved old Library/Float.thy to ComputeFloat

Added derivation lemmas for power series and theorems for the pi, arcus tangens and logarithm series

Make some Refute functions public so I can use them in Nitpick, use @{const_name} antiquotation whenever possible (some, like Lfp.lfp had been renamed since Tjark wrote Refute), and removed some "set"-related code that is no longer relevant in Isabelle2008. There's still some "set" code that needs to be ported; see TODO in the file.
