Classical and Quantum Fermions Linked by an Algebraic Deformation

Ali Mostafazadeh

We study the regular representation $ρ_{ζ}$ of the single-fermion algebra $A_{ζ}$ , i.e., $c^{2} = c^{+ 2} = 0$ , $c c^{+} + c^{+} c = ζ 1$ , for $ζ \in [0, 1]$ . We show that $ρ_{0}$ is a four-dimensio…

Symplectic tori in rational elliptic surfaces

Tolga Etgü, B. Doug Park

Let E(1)_p denote the rational elliptic surface with a single multiple fiber f_p of multiplicity p. We construct an infinite family of homologous non-isotopic symplectic tori repre…

Homologous Non-isotopic Symplectic Tori in Homotopy Rational Elliptic Surfaces

Tolga Etgü, B. Doug Park

Let E(1)_K denote the closed 4-manifold that is homotopy equivalent (hence homeomorphic) to the rational elliptic surface E(1) and is obtained by performing Fintushel-Stern knot su…
