Abstract
We study in this paper the Minkowski Symmetry Set (MSS) of a closed smooth curve gamma in the Minkowski plane. We answer the following question which is analogous to one concerning curves in Euclidean plane that was treated in [7]: given a point p on gamma, does there exist a bitangent pseudocircle that is tangent to gamma at both p and at some other point q on gamma? The answer is yes, but as pseudocircles with nonzero radii have two branches (connected components) it is possible to refine the above question to the following one: given a point p on gamma does there exist a branch of a pseudocircle that is tangent to gamma at both p and at some other point q on gamma? This question is motivated by the quest in [12] to define the Minkowski Blum medial axis, a counterpart of the Blum medial axis of curves in the Euclidean plane ([3]).
