On knotted real projective planes
Abstract
Let be a hyperbolic transformation. Let B be a new band attaching to L such that
is also a hyperbolic transformation. In this paper, we will study the relationship between the realizing surfaces
and
. If B is a noncoherent band to both L and
such that
is defined, then
and
are ambient isotopic, where RP2 is one of the standard real projective planes. We will study the triviality of
because as an application, RP2 can untangle some knotted sphere
with suitable conditions, when it is attached to
by the connected sum.
