New Signature Scheme Using Conjugacy Problem
We propose a new digital signature scheme based on a non-commutative group where the conjugacy search problem is hard and the conjugacy decision problem is feasible. We implement our signature schemeExpand

The Geography of Simply-Connected Symplectic Manifolds
By using the Seiberg-Witten invariant we show that the region under the Noether line in the lattice domain ℝ X ℝ is covered by minimal, simply connected, symplectic 4-manifolds.

SYMPLECTIC SURFACES IN SYMPLECTIC 4-MANIFOLDS
Let a closed, minimal, symplectic 4-manifold $X$ contain a symplectic surface $F$ such that the genus $g$ of $F$ is greater than or equal to one and the value $c_1(TX)[F]>g$. Then we show that theExpand
