Sub-Critical Closed String Field Theory in D Less Than 26

Michio Kaku

We construct the second quantized action for sub-critical closed string field theory with zero cosmological constant in dimensions , generalizing the non-polynomial…

Induced term and photon mass generation in 3+1 dimensions

M. Leblanc, R. MacKenzie, P. K. Panigrahi +1

Analysing a 3+1 dimensional model with four-Fermi interactions, we show that topological $\BF$ terms (both abelian and non-abelian) can be induced radiatively by massive fermions a…

W_{\infty} Gauge Transformations and the Electromagnetic Interactions of Electrons in the Lowest Landau Level

B. Sakita

We construct a gauge field theory of electrons in the lowest Landau level. For this purpose we introduce an external gauge potential such that its $W_{\infty…

Automatic structures and boundaries for graphs of groups

Walter D. Neumann, Michael Shapiro

We study the synchronous and asynchronous automatic structures on the fundamental group of a graph of groups in which each edge group is finite. Up to a natural equivalence relatio…

A note on Context Sensitive languages and Word Problems

Michael Shapiro

Anisimov and Seifert show that a group has a regular word problem ifand only if it is finite. Muller and Schupp (together with Dunwoody's accessibility result) show that a group ha…

The Electromagnetic Interactions of Electrons in the Lowest Landau Level

Rashmi Ray, B. Sakita

Starting from a system of planar electrons in a strong magnetic field normal to the plane, interacting with perturbing electromagnetic fields, an effective Lagrangian for the fermi…

The supergroup U(M/N) with regard to electronic Hamiltonians

Ko Okumura

We study the U(M/N) supergroup keeping in mind its connection with electronic Hamiltonians. It is explicitly shown that the generators of the supergroup U(N/N) can be expressed by…

Various condensed matter Hamiltonians in terms of U(2/2) operators and their symmetry structures

Ko Okumura

We rewrite various lattice Hamiltonian in condensed matter physics in terms of U(2/2) operators that we introduce. In this representation the symmetry structure of the models becom…
