| Research Abstract |
We studied intersections of essential laminations and Heegaard surfaces which give strongly irreducible Heegaard splittings in three dimensional manifolds. It is known that such Heegaard surfaces intersect essential surfaces in essential simple closed curves. We gave a similar result when Heegaard genus is two. We also gave some examples which give a phenomenon specific to non-compact objects.
