Wick Rotation on Noncommutative Space — •Thomas Ludwig¹, Harald Grosse², Gandalf Lechner², and Rainer Verch³ — ¹Universität Leipzig & MPI MIS Leipzig — ²Universität Wien — ³Universität Leipzig

We consider Euclidean Moyal space with commutative time and investigate ways to get from a Euclidean field theory to a Minkowskian quantum field theory. Two main approaches are discussed: firstly, we start with a Euclidean net of C*-algebras satisfying the so-called time-zero condition and construct a Minkowskian net by analytically continuing the representation of the remaining Euclidean symmetries to a unitary representation of the corresponding Poincare subgroup. Secondly, we present results concerning the analytic continuation of noncommutative Schwinger functions.
