In this paper,we discuss the blow-up of periodic solutions to a class of quasilinear hyperbolic systems in diagonal form,and make the accurate estimate of life-
The excitation functions of the evaporation residue formation probability of three heavy nuclei 194Pb, 200Pb and 206Pb are calculated by using a Langevin equati
A complete list of representatives of conjugacy classes of torsion in 4 × 4 integral symplectic group is given in this paper.There are 55 distinct such classes
Cross-sections for (n, 2n) reactions have been measured on stannum isotopes at the neutron energies of 13.5 to 14.6 MeV using the activation technique. Data are
This paper concerns with properties of solutions of a nonlinear diffusion problem in non-divergence form.By constructing proper test functions,it is proved that
