BOUNDED VARIATION ON THE SIERPINSKI GASKET

Under certain continuity conditions, we estimate upper and lower box dimensions of the graph of a function defined on the Sierpinski gasket. We also give an upper bound for Hausdorff dimension and box dimension of the graph of a function having finite energy. Further, we introduce two sets of definitions of bounded variation for a function defined on the Sierpinski gasket. We show that fractal dimension of the graph of a continuous function of bounded variation is log 3/log 2. We also prove that the class of all bounded variation functions is closed under arithmetic operations. Furthermore, we show that every function of bounded variation is continuous almost everywhere in the sense of log 3/log 2-dimensional Hausdorff measure.
