'Topological parallel world' constructed by modification of space-time along observables

We introduce a new concept, (topological) (vacuum) parallel world, ' which is a new tool to research submanifolds. Roughly speaking, Observables in (T)QFT’ is equal to `a (topological) modification of space-time.’ In other words, we give a new interpretation of observables. We give some examples associated with the Alexander polynomial, the Jones polynomial.
