Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract Multi-point initial boundary value problem for fourth order system of partial differential equations is considered. By new unknown function the problem is reduced to an equivalent nonlocal problem for system of hyperbolic equations of second order with dynamical condition. By the method of introduction functional parameters are constructed the algorithms for finding of solution to nonlocal problem for system of hyperbolic equations of second order with dynamical condition. Conditions of existence unique classical solution to nonlocal problem for system of hyperbolic equations of second order with dynamical condition are obtained in the terms of initial data. Criteria of unique solvability to multi-point initial boundary value problem for fourth order system of partial differential equations is established.
