Positive Solutions to Indefinite Problems

This book is devoted to the study of positive solutions to indefinite problems. The new technique developed in the book gives, as a byproduct, infinitely many subharmonic solutions and globally defined positive solutions with chaotic behaviour.

Aceasta carte este dedicata studiului solutiilor pozitive la probleme nedeterminate. Noua tehnica dezvoltata in carte ofera, ca produs secundar, infinit de multe solutii subarmonice si solutii pozitive definite la nivel global, cu comportament haotic.
