2.By use of upper and lower solution method and maximum and minimum principle,the estimates of blow-up rates for the positive solution of the heat equation with a nonlinear reaction term and a nonlinear boundary condition are presented,and the upper and lower bounds of the estimates have been...
Calculation of upper and lower bounds for eigenvalues by a boundary condition method: The quartic oscillator, hydrogen molecule ion, and helium atom In this paper, we study estimates for eigenvalues of the clamped plate\nproblem. A sharp upper bound for eigenvalues is given and the lower bound ...
Upper and lower bounds are calculated for the dispersion curves. They are rather close to each other in the cases of small electron-phonon couplings usual for real polar materials. To describe the dispersion in other materials, we suggest a simple fitting formula which can be applied at ...
upper and lower bounds was explained by the German mathematician K. Weier-strass; they are basic for the rigorous exposition of the fundamentals of mathematical analysis. Analogous to the concept of upper and lower bounds for sets of numbers has been the introduction of the concepts of upper ...
