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

Eiji Ogasa

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 (topolo…

Ribbon-moves of 2-knots: the torsion linking pairing and the $η$ -invariants of 2-knots

Eiji Ogasa

We discuss the ribbon-move for 2-knots, which is a local move. Let $K$ and $K^{'}$ be 2-knots. Then we have: Suppose that $K$ and $K^{'}$ are ribbon-move equivalent. (1) Let ${\mathrm {T…

Remarks on $n$ -dimensional Feynman diagrams, for example, which will appear in M-theory and in F-theory

Eiji Ogasa

We state some remarks on ` $n$ -dimensional Feynman diagrams' ( $n \in N$ ). There are different features between in the case of $n$ -dimensional Feynman diagrams( $n ≧ 3$ ) and in the 1…
