TL;DR: In this paper, the B-model origin of extended Picard-Fuchs equations satisfied by the Dbrane superpotential on compact Calabi-Yau threefolds is explained.
Abstract: We explain the B-model origin of extended Picard-Fuchs equations satisfied by the D-brane superpotential on compact Calabi-Yau threefolds. Via the Abel-Jacobi map, the domainwall tension is identified with a Poincare normal function--a transversal holomorphic section of the Griffiths intermediate Jacobian. Within this formalism, we derive the extended Picard-Fuchs equation associated with the mirror of the real quintic.

TL;DR: Using the asymmetric method, the analytic one-soliton solution of the CCQGLE is obtained for the first time and it is shown that the transmission of the soliton is controlled by changing the values of related parameters.
