This book deals with such important subjects as variational methods, the continuity method, parabolic equations on fiber bundles, ideas concerning points of con

Investigations in modem nonlinear analysis rely on ideas, methods and prob lems from various fields of mathematics, mechanics, physics and other applied science

When M. Vidyasagar wrote the first edition of Nonlinear Systems Analysis, most control theorists considered the subject of nonlinear systems a mystery. Since th
