We study subgroups G of GL n, R definable in o-minimal expansions M s Ε½ . Ε½. R, q, ΠΈ , . . . of a real closed field R. We prove several results such as: a G can be defined using just the field structure on R together with, if necessary, power Ε½ . functions, or an exponential function definable in M.

Let R be a one-dimensional noetherian domain containing the field Q of rational numbers. Let A be an A'-fibration over R. Then there exists HE A such that A is an A'-fibration over R[H]. As a consequence, if a,,, is free then A = R['].

## Abstract In this note we show: Let __R__ = γ€ˆ__R__, <, +, 0, …〉 be a semi‐bounded (respectively, linear) o‐minimal expansion of an ordered group, and __G__ a group definable in __R__ of linear dimension __m__ ([2]). Then __G__ is a definable extension of a bounded (respectively, definably compact
