Abstract
We provide a lower bound for the ratio between the ordinary and uniform exponent of both simultaneous Diophantine approximation and Diophantine approximation by linear forms in any dimension. This lower bound was conjectured by Schmidt and Summerer and already shown in dimension and . This lower bound is reached at regular systems presented in the context of parametric geometry of numbers, and thus optimal.
