1300. Philipp Hieronymi and Erik Walsberg On continuous functions definable in expansions of the ordered real additive group E-mail: Submission date: 10 September 2017 Abstract: Let R be an expansion of the ordered real additive group.
Then one
of the following holds: either every continuous function [0,1] →
R
definable in R is C^2 on an open dense subset of [0,1],
or every
C^2 function [0,1] → R definable in R is affine, or
every continuous function [0,1] → R is definable in
R. Mathematics Subject Classification: Primary 03C64 Secondary 03C40, 03D05, 03E15, 26A21, 54F45 Keywords and phrases: |
