積分方程和算子理論(IEOT)致力于出版當前的研究，在積分方程，算子理論和相關主題的重點線性方面的理論。該雜志報道了當前發展的全面范圍，從抽象理論到數值方法和應用到分析，物理，力學，工程和其他。該期刊由兩個部分組成:一個主要部分由參考文獻組成，另一個部分由重要結果、公開問題、信息等的簡短公告組成。

Integral Equations and Operator Theory (IEOT) is devoted to the publication of current research in integral equations, operator theory and related topics with emphasis on the linear aspects of the theory. The journal reports on the full scope of current developments from abstract theory to numerical methods and applications to analysis, physics, mechanics, engineering and others. The journal consists of two sections: a main section consisting of refereed papers and a second consisting of short announcements of important results, open problems, information, etc.
