We study thire quantum Peter-Weyl theory and the Woronowicz-Tannaka-Krein theorem. In the last chapter we discuss the orthogonal quantum group O+ N and nd an orthogonal basis of the invariant subspace for n = 2; 3 and a partial result for n = 4.enCompact Quantum GroupOrthogonal Quantum GroupO_N^+Tannaka-KreinPeter-WeylFinding a Peter-Weyl Basis for Small Representations of O_N^+Other
