Hi

Anyone who can tell me how to proove that there consists exactly 14 Bravais lattices or can point me to a reference where this is prooven?

Not a proof, but you may enjoy Nussbaum's "The mystery of the fifteenth Bravais lattice," Am J Phys 68(10) (2000) and Azaroff's rebuttal "No! to a fifteenth Bravais lattice," Am J Phys 70(2) (2002).
 
Any solid state textbook, Tinkham comes to mind as well as Kittel.
 
I haven't seen this proof in any solid state text, including Kittel (unless you mean his more advanced 'Quantum Theory of Solids' - haven't had to pleasure to read this yet). I would think this question is better suited for the mathematicians. Crystallography, although definitely an applied subject today, began as a pure mathematical subject.
 
From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
