Abstract
In [5] Phillips proved that one can obtain the additive group of any nonstandard model *ℤ of the ring ℤ of integers by using a linear mod 1 function h : F ℚ, where F is the α‐dimensional vector space over ℚ when α is the cardinality of *ℤ. In this connection it arises the question whether there are linear mod 1 functions which are neither addition nor quasi‐linear. We prove that this is the case.

## Abstract We prove that for each __β__, __γ__ < __ε__~0~ there exists__α__ < __ε__~0~ such that whenever __A__ ⊆ __ω__ is __α__ ‐large and __G__: __A__ → __β__ is such that (∀__a__ ∈ __A__)(psn(__G__ (__a__)) ≤ __a__), then there exists a __γ__ ‐large __C__ ⊆ __A__ on which __G__ is nondecreasing
