Nonlinear functional analysis and differential equations Book

That cover brings back delighted memories of leaving the library, clutching this tome, going back and forth between the menacing, red-eyed representatives of the cryptids within and the back cover, a wall-paper of newspaper headlines about monster sightings.


A thorough and well-written book, although I never bought into (and still don't) the mystical explanations that crop up at the end. That said, even when the book is all the way down its rabbit hole (Bigfoot hole?), it remains sober and at least vaguely scientific in its argument. Time to track this one down.
