【 摘 要 】

In this note we give several methods to construct nontrivial solutions to the equation d(yt) = sigma(y(t))dx(t) where x is a gamma-Holder R-d-valued signal with gamma is an element of(1/2, 1) and a is a function behaving like a power function |xi|(k), with K is an element of (0, 1). In this situation, classical Young integration techniques allow to get existence and uniqueness results whenever gamma(K + 1) > 1, while we focus on cases where gamma(K + 1) <= 1. Our analysis then relies on Zahle's extension (Zahle, 1998) of Young's integral allowing to cover the situation at hand. (C) 2017 Elsevier B.V. All rights reserved.
