Resumen:
In this note we study the norm convergence of multiple er-godic spherical averages from actions of word hyperbolic groups or moregeneraly strongly Markov groups. The objective is the generalization ofthe results by Bufetov, Khristoforov and Klimenko and by Pollicott andSharp. We use the techniques that Walsh introduced for proving the normconvergence of multiple ergodic averages from measure-preserving trans-formations and for integer valuated polynomials.
