變分法

內(nèi)容概要

　　《變分法（第4版）》是《變分法》第四版，主要講述在非線性偏微分方程和哈密頓系統(tǒng)中的應(yīng)用，繼第一版出版十八年再次全新呈現(xiàn)。整《變分法（第4版）》都做了大量的修改，僅500多條參考書目就將其價值大大提升。第四版中主要講述變分微積分，增加了該領(lǐng)域的最新進(jìn)展。這也是一部變分法學(xué)習(xí)的教程，特別講述了yamabe流的收斂和脹開現(xiàn)象以及最新研究發(fā)現(xiàn)的調(diào)和映射和曲面中熱流的向后小泡形成。

章節(jié)摘錄

版權(quán)頁：   插圖：   Hardy Space Methods The Hardy Hp-spaces play an important role in harmonic analysis.  In the theory of partial differential equations, the space H1 is of particular interest. For instance, the Calderón-Zygmund theorem, asserting that for 1 < p
