The disk embedding problem is of fundamental importance in the study of 4-dimensional topology.  I will discuss its significance and difficulty, including how disk embedding makes dimension four intrinsically different from other dimensions.  Then I will present some recent advances toward the existence and non-existence of embedded disks in 4-manifolds.

  1. Fixed points of symplectic/Hamiltonian circle actions

    A circle action on a manifold can be thought of as a periodic flow on a manifold (periodic dynamical system), or roughly a rotation of a manifold. During this talk, we consider symplectic/Hamiltonian circle actions on compact symplectic mani...

  2. A modified separation method to solve a heat-transfer boundary value problem

    We derive a general solution of the heat equation through two modied separation methods. The obtained solution is expressed as linearly combined kernel solutions in terms of Hermite polynomials, which appears to provide an explanation of non...

  3. Arithmetic of elliptic curves

    Elliptic curves defined over the rationals satisfy two finiteness properties; its group of rational points is a finitely generated abelian group and it has only finitely many points with integral coordinates. Bhargava and his collaborators e...
