In this work we write down Seiberg-Witten equations with negative sign. We give some explicit solutions to these equations on R-4 which are related with the famous Dirac monopole. We also point out a relationship between Seiberg-Witten equations with negative sign and Freud equations which are stated on Minkowski space R-1,R-3.
