Persistence : A Digit Problem
We examine the persistence of a number, defined as the number of iterations of the function which multiplies the digits of a number until one reaches a single digit number. We give numerical evidence supporting Sloane’s 1973 conjecture that there exists a maximum persistence for every base. In particular, we give evidence that the maximum persistence in each base 2 through 12 is 1, 3, 3, 6, 5, ...
متن کاملPersistence problem in two-dimensional fluid turbulence.
We present a natural framework for studying the persistence problem in two-dimensional fluid turbulence by using the Okubo-Weiss parameter Λ to distinguish between vortical and extensional regions. We then use a direct numerical simulation of the two-dimensional, incompressible Navier-Stokes equation with Ekman friction to study probability distribution functions (PDFs) of the persistence times...
متن کاملMisalignment on the Persistence of Inflation in Iran
The purpose of this study is to investigate the impact of exchange rate misalignment on inflation persistence. For this purpose, Vector Auto Regression method and Markov Switching model is used for quarterly data during 1989:4 -2014:3. The results show that, the impact of liquidity growth and exchange rate misalignment on inflation persistence is positive. On the other hand, GDP growth has a ne...
متن کاملon Persistence
Next, persistence through time. I take the view that nothing endures identically through time. (Except universals, if such there be; their loci would coincide with relations of qualitative match, would indeed constitute these relations, so they would commit no violations of Humean Supervenience.) Persisting particulars consist of temporal parts, united by various kinds of continuity. To the ext...
متن کاملOn Level persistence (Relevant level persistence numbers)
The purpose of this note is to describe a new set of numerical invariants, the relevant level persistence numbers, and make explicit their relationship with the four types of bar codes, a more familiar set of complete invariants for level persistence. The paper provides the opportunity to compare level persistence with the persistence introduced by EdelsbrunnerLetscher-Zomorodian called in this...
