The classical exchange algebra satisfied by the monodromy matrix of the nonlinear sigma model on a supercoset target with Z2n grading is derived using a first-o
Conformal invariance and conserved quantities for a higher-order Lagrange system by Lie point transformation of groups are studied.The differential equation of
The influences of Δ quartet,especially Δ- and Δ0 particles,on the neutrino scatting and cooling properties of neutron stars are discussed.The results show th
Using an isobaric method,the symmetry-energy coefficient (asym) of a neutron-rich nucleus is obtained from experimental binding energies.The shell effects are s
