Linear algebra c-4: quadratic equations in two or three variables

Here we collect all tables of contents of all the books on mathematics I have written so far for the publisher. In the rst list the topics are grouped according to their headlines, so the reader quickly can get an idea of where to search for a given topic. In order not to make the titles too long I have in the numbering added a for a compendium b for practical solution procedures (standard methods etc.) e for examples. The ideal situation would of course be that all major topics were supplied with all three forms of books, but this would be too much for a single man to write within a limited time. After the rst short review follows a more detailed review of the contents of each book. Only Linear Algebra has been supplied with a short index. The plan in the future is also to make indices of every other book as well, possibly supplied by an index of all books. This cannot be done for obvious reasons during the rst couple of years, because this work is very big, indeed. It is my hope that the present list can help the reader to navigate through this rather big collection of books Finally, since this list from time to time will be updated, one should always check when this introduction has been signed. If a mathematical topic is not on this list, it still could be published, so the reader should also check for possible new books, which have not been included in this list yet. Unfortunately errors cannot be avoided in a rst edition of a work of this type. However, the author has tried to put them on a minimum, hoping that the reader will meet with sympathy the errors which do occur in the text.
