This article proposes a notional defined contribution (NDC) mechanism to ensure pension mobility for the 150 million migrating workers in China during both the accumulation and drawdown phases. Planned governance would ensure independence from the three existing pension systems. An appropriately structured NDC plan of this type is shown to be viable by reference to a previously developed model …

Let k be an arbitrary field and Q be an acyclic quiver of tame type (that is, of type˜ An, ˜Dn, ˜E6, ˜E7, ˜E8). Consider the path algebra kQ, the category of finite-dimensional right modules mod-kQ, and the minimal positive imaginary root of Q, denoted by δ. In the first part of the paper, we deduce that the Gabriel–Roiter (GR) inclusions in preprojective indecomposables and homoge…

We provide a condition for systolic complexes implying hyperbolicity, which is weaker than 7-systolicity.

We present a new approach to an equivariant version of Farber’s topological complexity called invariant topological complexity. It seems that the presented approach is more adequate for the analysis of impact of a symmetry on a motion planning algorithm than the one introduced and studied by Colman and Grant. We show many bounds for the invariant topological complexity comparing it with a…

We define a new type of Hardy–Orlicz spaces of conformal mappings on the unit disk where in place of the value |f(x)| we consider the intrinsic path distance between f(x) and f(0) in the image domain. We show that if the Orlicz function is doubling then these two spaces are actually the same, and we give an example when the intrinsic Hardy–Orlicz space is strictly smaller.

We give a short argument why the tensor product semi-norm on K ⊗k L is multiplicative when k is an algebraically closed valued field and K and L are valued extensions (valued in R). When the valuation on k is non-trivial we use the fact that ACVF, the theory of algebraically closed (non-trivially) valued fields, has quantifier elimination.
