           ``Some Integral Geometry Problems''

＜研究発表要旨＞
This talk concerns the uniqueness in the problems of integral geometry for
2-forms, and related general type of integral geometry problems are also 
presented. These problems are appeared in the study of reconstruction of the
Riemanian metric from the boundary distance function. They have applications,
for example, in geophysics in connection with the study of the velocities 
distribution of the propagation of elastic waves inside terrestrial globe.
