Box-counting fractal strings, zeta functions, and equivalent forms of Minkowski dimension

We discuss a number of techniques for determining the Minkowski dimension of bounded subsets of some Euclidean space of any dimension, including: the box-counting dimension and equivalent definitions based on various box-counting functions ; the similarity dimension via the Moran equation (at least in the case of self-similar sets) ; the order of the (box-)counting function ; the classic result on compact subsets of the real line due to Besicovitch and Taylor, as adapted to the theory of fractal strings ; and the abscissae of convergence of new classes of zeta functions. Specifically, we define box-counting zeta functions of infinite bounded subsets of Euclidean space and discuss results from \cite{;LapRaZu}; pertaining to distance and tube zeta functions. Appealing to an analysis of these zeta functions allows for the development of theories of complex dimensions for bounded sets in Euclidean space, extending techniques and results regarding (ordinary) fractal strings obtained by the first author and van Frankenhuijsen.
