WALSH ANALYSIS OF CONTINUOUS MEASURES

Abstract

WE GIVE A CHARACTERIZATION OF THE CONTINUITY OF MEASURES ON LOCALLY COMPACT METRIZABLE GROUPS G, BASED ON THE WALSH ANALYSIS OF MEASURES. WE USE THIS CHARACTERIZATION TO PROVE THAT FOR EVERY COMPACT SET K OF CONTINUOUS MEASURES ON G THERE EXIST A CONTINUOUS AND SINGULAR MEASURE V SUCH THAT ITS CONVOLUTION WITH K GIVES MEASURES ABSOLUTELY CONTINUOUS WITH RESPECT TO THE LEFT HAAR OF G. THE MEASURE V IS A RIESZ PRODUCT WITH WALSH FUNCTIONS OF THE TYPE DN=Π/J=0 (1+AJWΛJ(X))DX. (1) WE ALSO STUDY THE HAUSDORFF DIMENSION OF BOREL SETS OF POSITIVE MEASURE M, WHERE M IS OF THE TYPE (1), AND THEIR RELATION WITH NORMAL NUMBERS.
