A new proof of the existence of hierarchies of Poisson--Nijenhuis structuresJ. MonterdeDept. de Geometria i Topologia, Universitat de València,Avda. Vicent Andrés Estellés, 1, E-46100-Burjassot (València) -- SPAIN E-mail: monterde@uv.es Abstract: Given a Poisson--Nijenhuis manifold, a two-parameter family of Poisson--Nijenhuis structures can be defined. As a consequence we obtain a new and noninductive proof of the existence of hierarchies of Poisson--Nijenhuis structures. Keywords: Poisson--Nijenhuis structure; Gerstenhaber algebra; generating operator. Classification (MSC2000): 58F05, 53C15.; 58F07. Full text of the article:
