I would like to know if anyone has an electronic copy of the following paper:
MR0279626 (43 #5347) Kato, Tosio Linear evolution equations of "hyperbolic'' type. J. Fac. Sci. Univ. Tokyo Sect. I 17 (1970), 241–258.
In my search, the best result I found was the second article published by the same author and an answer by Willie Wong here on MathOverflow quoting this article.
Any information is welcome, for example, if this article is published in a book.
