The mathematics of market timing

market timing returns symmetric? If it is hard to obtain above average returns by market timing, is it also hard to obtain below average returns? What is the most basic mathematics of market timing? I try ... mathematics. Using perfect hindsight, it is easy to identify the best and worst possible market timing portfolios, which form the boundaries of the feasible return paths for all market timing portfolios, i.e

Asymptotics for general nonstationary fractionally integrated processes without prehistoric influence

Language as resource: a key notion for understanding the complexity of mathematics learning

The thinking of language as resource in mathematics education research has been more metaphorical than conceptual so far. This article provides grounds and reasons for the theorization of language as ... meaning in the immediacy of situations embedded in cultures of school mathematics and the official language of instruction. In the midst of social and personal relationships and diverse experiences in/of

The Conformal Flow of Metrics and the General Penrose Inequality

The Fundamental Problem of General Proof Theory

I see the question what it is that makes an inference valid and thereby gives a proof its epistemic power as the most fundamental problem of general proof theory. It has been surprisingly neglected ... of general proof theory, a problem that the foundation of that discipline should try to tackle. It has been surprisingly neglected in logic and philosophy of mathematics. Proofs have certainly since

Generalised Spin Structures in General Relativity

Generalised spin structures describe spinor fields that are coupled to both general relativity and gauge theory. We classify those generalised spin structures for which the corresponding fields admit ... are coupled to general relativity (GR) as well as gauge theory. In the absence of gauge fields, space–time transformations of spinors coupled to GR can be understood by considering pairs (g, ψ) of a
