On 2-knots and Connected Sums with Projective Planes Longo, Vincent
There have been examples provided in the past of connected sums of a knotted sphere with an unknotted projective plane which are isotopic to the unknotted projective plane. It is an open question as to whether the connected sum of an odd twist spun knot and an unknotted projective plane is isotopic to the unknotted projective plane, but in this talk we discuss when the result is known to be true after a trivial internal stabilization.
