چکیده | ||
In this paper, we introduce a new type of graph contraction using a special class of functions and give a best proximity point theorem for this contraction in complete metric spaces endowed with a graph under two different conditions. We then support our main theorem by a non-trivial example and give some consequences of best proximity point of it for usual graphs. | ||

چکیده [English] | ||
در این مقاله، ما کلاس خاصی از نوعی جدید از انقباض گرافی را معرفی کرده و بهترین نقطه تقریب را برای این انقباض در فضاهای متریک کامل مجهز به گراف تحت دو شرط متفاوت مورد بررسی قرار میدهیم. سپس به کمک یک مثال اهمیت و وجود قضیه اصلی را نشان داده و برخی از نتایج بهترین نقطه تقریب را برای گرافهای معمولی بیان میکنیم. | ||
کلیدواژهها [English] | ||
