We show that there exists a submanifold diffeomorphic to $S^2 \sqcup S^2$ sitting inside $S^4$, whose components are separated by an integer homology 3-sphere $Y$ (i.e., a manifold with the same integer homology of $S^3$), but not by the standard $S^3$.
This is joint work with Marco Golla.
Note that the seminar will not be held on its usual day and will be held at the Faculty of Education (PEF UL).
Vljudno vabljeni! B. Gabrovšek and D. Repovš**
