This Lecture Notes volume, a sequel to volumes 1108 and 1214,
presents to English speaking readers further two issues of the
Voronezh University Press series "Novoe v global'nom analize" (New
Developments in Global Analysis). These issues, published in Russian
March, 1987 and in November, 1987, are entitled "Global Analysis
and Mathematical Physics" and "Geometry and Theory of Singularities

papers giving detailed accounts of research results. Short
communications and the survey article of Yu.P.Solov'ev (March, 1987) are
omitted here (the material of the latter will be published in
English elsewhere).
