我们研究了De Rham函数:满足函数方程的唯一连续(不可微)函数。我们证明了它的逐点Holder正则性随点的不同而有很大的不同,并且填充区间的值是参数化分形集的,其中是具有Holder指数的点集。我们还证明了热力学形式(增量方法)对于De Rham函数是成立的:我们有一个启发式公式,该公式将As的衰变顺序与的Hausdorff维度联系起来。
We study the de Rham function: the unique continuous (nowhere differentiable) function with satisfying the functional equation . We show that its pointwise Holder regularity differs widely from point to point, and the values of fill an interval parametrizing the fractal sets , where is the set of points with Holder exponent . We also prove that the thermodynamic formalism (increment method) holds for the de Rham function: we have a heuristic formula relating the order of decay of as with the Hausdorff dimension of .
