Abstract

Fekete, Jordán and Kaszanitzky (Graphs Combin 31:585–599, 2015) characterised the graphs which can be realised as 2-dimensional, infinitesimally rigid, bar-joint frameworks in which two given vertices are coincident. We formulate a conjecture which would extend their characterisation to an arbitrary set T of vertices and verify our conjecture when \(|T|=3\).
