摘    要：

The intermediate dimensions are a family of dimensions which lie between two familiar notions of fractal dimension, namely the Hausdorff and box dimensions. After defining the intermediate dimensions, we will describe the form they take for several different classes of fractal sets. In particular, we will consider polynomial sequence sets, the graph of the popcorn function, and self-affine Bedford-McMullen carpets. We will then state a necessary and sufficient condition which determines whether a given function can be realised as the intermediate dimensions of a subset of Euclidean space. In this survey-style talk, results from several different projects will be mentioned, three of which are joint with Haipeng Chen, Istvan Kolossvary and Alex Rutar respectively.
