【 摘 要 】

We study non-geometric five-branes in heterotic supergravity where the first order α'-corrections are present. By performing the α'-corrected T-duality transformations of the heterotic NS5-brane solutions, we obtain the exotic 52/2-brane solutions associated with the symmetric, the neutral and the gauge NS5-branes. We find that the symmetric 52/2-brane, and the neutral 52/2-brane at O(α'), are T-folds while the gauge 52/2-brane is not a T-fold. This proceeding is based on the work [1] where the details that are omitted in this manuscript are found.
