References

    This is an incomplete list. I have found these books/articles to be very helpful in getting started in this subject except for the last one which is quite technical. I have also provided further links to related web pages in case you are interested. Unfortunately, I cannot think of any nontechnical references for multidimensional tunneling. However the following list also addresses the issue.
