Waves and oscillations in solar and space plasmas are an obvious
manifestation of the dynamical character of space plasmas. Waves can
transport energy and momentum which can heat the plasma. They can also
transport information about the medium in which they propagate. One of the
most exciting branches of solar and space plasma physics is the
seismology of the solar interior and atmosphere where wave characteristics
(frequency, amplitude, phase, lifetime) are used to derive plasma
and field parameters which cannot be measured in the solar atmosphere
(magnetic field, density, transport coefficients, substructure of the
medium) or in the solar interior (temperature inhomogeneities, plasma flows,
subsurface structure of active regions and sunspots). The aims of this
session are to review recent theoretical and observational findings in this
field with special emphasis on the interdisciplinarity between the
seismology of the solar interior and solar atmosphere. In addition, we will
explore the many connections that exist between helioseismology and the
seismology of the Earth (studies of wave propagation through complex media,
finite-wavelength tomography, large-scale inverse problems, etc).
