<P>Number theory, spectral geometry, and fractal geometry are interlinked in this in-depth study of the vibrations of fractal strings, that is, one-dimensional drums with fractal boundary. In this book The Riemann hypothesis is given a natural geometric reformulation in the context of vibrating fractal strings. The book also offers explicit formulas extended to apply to the geometric, spectral, and dynamic zeta functions associated with a fractal. In addition, numerous theorems, examples, remarks and illustrations enrich the text. Throughout the book new results are examined. The final chapter gives a new definition of fractality as the presence of nonreal complex dimensions with positive real parts. The significant studies and problems illuminated in this work may be used in a classroom setting at the graduate level. The book will further appeal to students and researchers in number theory, fractal geometry, dynamical systems, spectral geometry, and mathematical physics.</P>
