The booklet demonstrates the improvement of essential geometry on domain names of homogeneous areas given that 1990. It covers quite a lot of themes, together with research on multidimensional Euclidean domain names and Riemannian symmetric areas of arbitrary ranks in addition to contemporary paintings on section house and the Heisenberg team. The booklet comprises many major fresh effects, a few of them hitherto unpublished, between which might be mentioned forte theorems for numerous sessions of capabilities, far-reaching generalizations of the two-radii challenge, the fashionable types of the Pompeiu challenge, and specific reconst. learn more...

Consider some basic properties of the mapping ????????,???? : ???? → ????????,???? (???? ). ′ First suppose that ???? ∈ (ℰ????,???? ∩ ???? ???? +????+????+2 )(ℝ???? ) for some ???? ∈ ℤ+ .
