Sign language is used as a communication medium among deaf and dumb people to convey the message with each other. A person who can talk and hear properly (normal person) cannot communicate with deaf and dumb person unless he/she is familiar with sign language. Same case is applicable when a deaf and dumb person wants to communicate with a normal person or(More)
This paper reviews progress on the Fractional Quantum Hall Effect (FQHE) based on what we term hamiltonian theories, i.e., theories that proceed from the microscopic electronic hamiltonian to the final solution via a sequence of transformations and approximations, either in the hamil-tonian or path integral approach, as compared to theories based on exact(More)
The hamiltonian theory of the fractional quantum Hall effect (FQHE) is derived and used to answer a large number of qualitative and quantitative questions. After some preliminaries, the complementary approach based on the trial wavefunctions of Laughlin and Jain is reviewed since it inspires the hamiltonian approach. A critical survey of vortices, the(More)
The linear complementarity problem (q, A) with data A ∈ R n×n and q ∈ R n involves finding a nonnegative z ∈ R n such that Az + q ≥ 0 and z t (Az + q) = 0. Cottle and Stone introduced the class of P 1-matrices and showed that if A is in P 1 \Q, then K(A) (the set of all q for which (q, A) has a solution) is a half-space and (q, A) has a unique solution for(More)
