《Calculus of variations and partial differential equations of the first order Part l: Partial Diffent》求取 ⇩

1965《Calculus of variations and partial differential equations of the first order Part l: Partial Diffent》由于是年代较久的资料都绝版了,几乎不可能购买到实物。如果大家为了学习确实需要,可向博主求助其电子版PDF文件(由 1965 Holden-Day 出版的版本) 。对合法合规的求助,我会当即受理并将下载地址发送给你。
