Book Description
This book solves a problem that has been open for over 20years---the complete classification of structurally stablequadratic vector fields modulo limit cycles. The 1950s saw thefirst real impetus given to the development of the qualitativetheory of quadratic vector fields, although prior and ongoinginterest in the topic can be shown by the more than 800 papersthat have been published on the subject. One of the problems inthe qualitative theory of quadratic vector fields is theclassification of all structurally stable ones: In this work theauthors solve this problem completely modulo limit cycles andgive all possible phase portraits for such structurally stablequadratic vector fields. ...
