   Let Q=qkk≥1 be a sequence of positive integers with qk≥2 for all k≥1. Then every x∈[0,1] is attached with a Cantor series expansion of the formx=ϵ1(x)q1+ϵ2(x)q1q2+⋯+ϵn(x)q1⋯qn+⋯. We study inhomogeneous and simultaneous Diophantine approximation in Cantor series expansions. Several versions of generalized shrinking target sets are defined in our framework. We will give a complete metric theory of these object sets in the sense of Lebesgue measure, Hausdorff measure and Hausdorff dimension.

   We answer the question: If a vacuum sector Hamiltonian is regularized by an energy cutoff, how is the one-kink sector Hamiltonian regularized? We find that it is not regularized by an energy cutoff, indeed normal modes of all energies are present in the kink Hamiltonian, but rather the decomposition of the field into normal mode operators yields coefficients which lie on a constrained surface that forces them to become small for energies above the cutoff. This explains the old observation that an energy cutoff of the kink Hamiltonian leads to an incorrect one-loop kink mass. To arrive at our conclusion, we impose that the regularized kink sector Hamiltonian is unitarily equivalent to the regularized vacuum sector Hamiltonian. This condition implies that the two regularized Hamiltonians have the same spectrum and so guarantees that the kink Hamiltonian yields the correct kink mass.
