ON SMOOTHNESS OF THE SOLUTION TO A NONLOCAL BOUNDARY VALUE PROBLEM OF PERIODIC TYPE FOR A FOURTH-ORDER MIXED-TYPE EQUATION OF THE SECOND KIND
##submission.downloads##
Ushbu maqolada biz modifitsirlangan Galerkin usuli, aprior baholash va “"-
regulyarizatsiya” usullari yordamida Sobolev fazolarida to’rtinchi tartibli ikkinchi
tur aralash tipdagi tenglama uchun davriy nolokal chegaraviy masala yechimining
mavjudligi va yagonaligini hamda silliqligini o’rganamiz.
