About covering maps and sections! @Jason deVito I think there might be a typo in your solution |

Infinitely sheeted covering spaces! @JasonDeVito But since any covering space of a manifold has to be a manifold, wouldn't all the covering spaces of a connected sum of tori be homeomorphic to a connected sum of tori? |

About covering maps and sections! Ok. Maybe someone else could give a more thorough explanation! |

About covering maps and sections! @rschwieb yes,it cast doubt on my solution...I am no longer sure that what I said holds...maybe you could shed some light. |

Infinitely sheeted covering spaces! Yes you are correct. My topology seems to be rusty...in this case wouldn't the proper subgroup of the fundamental group of the connected sum of tori be infinite cyclic then? Since this corresponds to some cover of the connected sum of tori then it would answer the op's question I think. |

Spectral Theorem @ Robert Israel: so is that all what the problem is asking? Namely to assert that the diagonal entries of the matrix A will be $\pm 1$ after diagonalization? It seems too simple! |

Spectral Theorem @ froggie: thanks! Regarding the question the only other thing I can get is that the matrix A will have real eigenvalues. |

Spectral Theorem Does it suffice to say something along the lines: since the matrix is symmetric and orthogonal, then the matrix A would be normal, so there is some orthogonal matrix P such that $P^tAP$ is a diagonal matrix whose entries are all 1s. Would this suffice or is it asking for more, sth else?? Thanks |

Spectral Theorem @gedgar: yes thats correct...however my trouble is on how to phrase my answer. |
