Parity-Based Level-Set Approach to the Collatz Conjecture

Mathematics
The Collatz conjecture concerns the iteration of the map f(n)=3n+1 for odd n and f(n)=n/2 for even n. In this paper, we study the level sets lx={n∈N∣L(n)=x}, where L(n) denotes the Collatz length.

On Gradual Sets, Hesitant Fuzzy Sets, and Representation Theorems

IEEE Access
We analyze the connection between two perspectives when defining fuzzy sets: the viewpoint of mappings and the viewpoint of families of level cuts. This analysis is mathematically supported by the framework of a categorical adjunction, which serves as a ...

Dynamic Level Sets

CoRR
A mathematical concept is identified and analyzed that is implicit in the 2012 paper Turing Incomputable Computation, presented at the Alan Turing Centenary Conference (Turing-100, Manchester). The concept, called dynamic level sets, is distinct from mathematical concepts in the standard literature on dynamical systems, topology, and computability ...

Un método numérico híbrido para capturar los choques en leyes de conservación escalares

Revista Integración, 2010
En este trabajo se estudia numéricamente la aproximación del problema de Cauchy para una ley de conservación escalar, utilizando una técnica mixta que combina los principios de volúmenes finitos y de conjuntos de nivel para capturar con alto orden la ...

Level sets of infinite length

Commentarii Mathematici Helvetici, 1978
The geometry of level sets plays an important role in the analysis of various function-theoretic problems. Often, however, the level sets are so complicated that one must either choose sets associated with special levels (see [3], [4]) or resort to the approximation of level sets by shorter curves (see[l, pp. 550-553]).

Solving the Variational Inequality Problem Defined on Intersection of Finite Level Sets

Abstract and Applied Analysis, 2013
Consider the variational inequality VI(C,F) of finding a point x*∈C satisfying the property 〈Fx*,x-x*〉≥0, for all x∈C, where C is the intersection of finite level sets of convex functions defined on a real Hilbert space H and F:H→H is an L-Lipschitzian ...
