i apologize, if my thread is not appropriate in proper room. But can someone help me to find a mathematic paper, because i can't find it in internet or elsewhere. This is the paper: Lifschitz, E.A., Fixed point theorems for operators in strongly convex spaces, Voronez.

Gos. Univ. Trudy Mat. Fak. 16 (1975), 23–28. Thanks a lot....
