By introducing a newconcept called Varialional Integral, a new method to systematically study the inverseproblem in calculus of rariations is given. Using this new method to the elastodynamicsand hydrodynamics of viscous fhuids some kinds of variaiional principles andgeneralized variational prineiples are obtained respectively.展开更多
Let P(z) be a polynomial of degree n which does not vanish in |z| 〈k, k≥ 1. It is known that for each 0 〈 s 〈 n and 1 ≤ R ≤ k,M(P(s),R)≤(1/(R^s+k^s)[{d(s)/dx(s)(1+x^n)}x=1]((R+k)/(1+k)...Let P(z) be a polynomial of degree n which does not vanish in |z| 〈k, k≥ 1. It is known that for each 0 〈 s 〈 n and 1 ≤ R ≤ k,M(P(s),R)≤(1/(R^s+k^s)[{d(s)/dx(s)(1+x^n)}x=1]((R+k)/(1+k)^nM(P,1). In this paper, we obtain certain extensions and refinements of this inequality by in- volving binomial coefficients and some of the coefficients of the polynomial P(z).展开更多
