Supersymmetric Euclidean field theories and K-theory

We construct spaces of 1-dimensional supersymmetric Euclidean field theories and show that they represent real or complex K-theory. This is done without prescribing the space of states in the definition of field theory. (C) 2020 Elsevier B.V. All rights reserved.
