A proof that the three-dimensional Gauss algorithm is strongly
convergent almost everywhere is given. This algorithm is
equivalent to Brun's algorithm and to the modified
Jacobi-Perron algorithm considered by Podsypanin and
Schweiger. The proof involves the rigorous computer assisted
estimation of the largest Lyapunov exponent of a cocycle
associated to the algorithm. To the best of my knowledge,
this is the first proof of almost everywhere strong
convergence of a Jacobi-Perron type algorithm in dimension
greater than two.
