Comment on the paper by Arik,Gün and Yildiz (hep-th/0212129) on "Invariance Quantum Group of Fermionic Oscillator"
R. Parthasarathy, K. S. Viswanathan
A non-trivial q-deformation of the fermionic oscillator proposed by us in 1991 is recalled in view of the result of the paper cited in the title.
Induced Rigid String Action From Fermions
R. Parthasarathy, K. S. Viswanathan
From the Dirac action on the world sheet, an effective action is obtained by integrating over the 4-dimensional fermion fields pulled back to the world sheet. This action consists…
Harmonic Maps and Self-Dual Equations for Immersed Surfaces
R. Parthasarathy, K. S. Viswanathan
The immersion of the string world sheet, regarded as a Riemann surface, in and is described by the generalized Gauss map. When the Gauss map is harmonic or equivalently…
Extrinsic Curvature Induced 2-d Gravity
K. S. Viswanathan, R. Parthasarathy
Abtract: 2-dimensional fermions are coupled to extrinsic geometry of a conformally immersed surface in through gauge coupling. By integrating out the fermions, we obtai…
