From the reviews:
"The book presents a broad survey of the results in an interesting area, where the harmonic analysis and differential and integral equations interact in a fruitful way. The authors themselves have contributed a lot to the subject. The book will be interesting to those working in the border areas between analysis, integral geometry and Lie groups representation theory." (Mark Agranovsky, Mathematical Reviews, March, 2014)
