Limit Cases of the Palais-Smale Condition, inspite of its success in dealing with one-dimensional variational problems like geodesics (see Birkhoff’s Theorem I.4.4, for example, or Palais’ work on closed geodesics), the Palais-Smale condition could never play a role in the solution of “interesting” variational problems in higher dimensi

The book gives

Light is produced by the radiative transition of the product from the excited state to the ground state (for further details see, e.g., Mc Capra 1978; Wampler 1978). Of the various luminous forms that have been investi

The conclusions drawn from this review must remain tentative due to the small nu
