By means of variational structure and Z_2 group index theory,we obtain a estimate for number of multiple periodic solutions to second-order neutral functional differential equations (cx(t)+x(t-T)+cx(t-2r))"-x(t-T)+λf(t,x(t),x(t-T),x(t-2T))=0.

By means of variational structure and Z_2 group index theory,infinitely many solutions of boundary value problems for second-order ordinary differential equations u″(t)-u(t)+f(t,u(t))=0,0<t<1,u′(0)=0,α_1u(1)+u′(1)=0, are obtained,whereα_1>-1/2.

补充资料:AR指标
AR指标——
AR指标又称人气指标或买卖气势指标,是反映市场当前情况下多空双方争斗结果的指标之一。市场人气旺则多方占优,买入活跃,股价上涨;反之,人气低落,交易稀少,人心思逃,则股价就会下跌。AR指标的计算公式和参数为:多方强度=H-0,空方强度=O-L。H—当日的最高价,L—当日的最低价,O—当日的开盘价。AR(N)=P1/P2×100;P1(N)=∑(H-O),P2(N)=∑(O-L)。从式中可以看出,AR表示N天以来多空双方总的强度的比值。
