  1. One of the main character of this paper is to present a new way of how to use a mountain pass theorem to prove the existence as to the dirichlet problem, without assuming conditions ( ar ), the other is that we have made great improvements as to the important condition of [ 6 ], in other words, we may delete the condition on which f ( x, t ) / t is nbndecreasing with respect to t 0, a. e. x

    這篇文章的一個主要特徵是提出一種新的方法運用山路引理證明了在沒有條件( ar )的情形下dirichlet問題正解的存在性,另一個是我們對文獻[ 6 ]中的重要條件做了巨大的改進,即我們可刪去f ( x , t ) / t對a . e . x關于t在[ 0 , + )上單調遞增。
  2. In this dissertation, we firstly prove that any dirichlet problem is indeed equal to a voltages problem of networks. we give five solutions to dirichlet problem in two dimensions ; among these five solutions, we prove that the iteration solution and the solution of relaxations are exponential convergence, then we estimate their respective convergence rates ; secondly, we discuss random walks on general networks, prove that there is an one to one correspondence between networks and reversible ergodic markov chains ; thirdly, we give probabilistic interpretation of voltages for general networks : when a unit voltage is applied between a and b, making va = 1 and vb = 0, the voltage vx at any point x represents the probability that a walker starting from x will return to a before reaching b ; furthermore, we study the relationship between effective resistance and escape probability : starting at a, the probability that the walk reaches b before returning to a is the ratio of the effective conductance and the total conductance

    本文證明了任何邊值的dirichlet問題都可轉化為求解電路電壓的問題:給出了計算平面格點上dirichlet問題的5種方法:證明了迭代法和松馳法都是指數收斂的,並分別給出收斂速度的估計;討論了一般電路上的隨機徘徊,驗證了電路與可逆的遍歷markov鏈是一一對應的;給出了電路電壓的概率解釋:當把1伏電壓加於a , b兩端,使得v _ a = 1 , v _ b = 0時,則x點的電壓v _ x表示對應的markov鏈中,從x出發,到達b之前到達a的概率;進一步地,給出了逃離概率與有效電阻之間的關系:從a出發,在到達b之前到達a的概率為有效傳導率與通過a的總傳導率之比。
