Research Abstract

The main research results obtained in the research period which began in 2010 and ended in 2012 are the following:
(1). A version of Hilbert’s 13thproblem for infinitely differentiable functions, which remained to be open, has been solved constructively.
(2). Embedding of Collatz mapping into a certain one-dimensional compact dynamical system has enabled us to apply the theory of topological dynamics to its famous conjecture
