About the traversability of thin-shell wormholes

Traversability in relation with tides across thin-shell wormholes is analyzed. Conditions for a safe travel through wormhole throat are established terms of the parameters characterizing geometries and reasonable assumptions regarding travellers motion. Most convenient turn to include physically interesting example connecting locally flat submanifolds as those associated gauge cosmic strings. A certain relaxation conditions imposed corresponding extension set admissible configurations also briefly discussed.
