La teoria di Morse negli spazi di Banach
No full textSi propone una via più semplice, basata sull’impiego di una duplice norma, per estendere la teoria di Morse alle varietà modellate su spazi di Banach.We propose a simple way, based on the use of a double norm, to extend Morse theory at the varieties modelled on Banach spaces
Minimum free energy for a rigid heat conductor and application to a discrete spectrum model
No full textA general closed expression is given for the minimum free energy for a rigid heat conductor with memory effects. This formula, derived in the frequency domain, is related to the maximum recoverable work we can obtain from the material at a given state, which is characterized by the temperature and the past history of its gradient. Another explicit formula of the minimum free energy is also derived and used to obtain the results related to the particular case of a discrete spectrum model material response
Minimum free energy in linear thermoelectromagnetism
No full textA closed expression is given for the minimum free energy of a linear thermoelectromagnetic conductor, whose constitutive equations relative to the electric current density and to the heat flux have memory effects. This expression, derived in the frequency domain, is related to the maximum recoverable work, which can be obtained from a given state of the material. Another equivalent expression of the minimum free energy is deduced; it allows us to give explicit formulae for the case of a discrete spectrum model
