چکیده

فرض کنیم فضای نرمدار ناارشمیدسی اعداد حقیقی باشد. معادله دیفرانسیل خطی ناهمگن مرتبه‌ دوم با ضرایب غیرثابت را در نظر می‌گیریم که در آن توابع داده شده پیوسته هستند. در این مقاله پایداری هایرز-اولام این معادله را در فضای نرمدار ناارشمیدسی اعداد حقیقی ثابت می‌کنیم. معادله دیفرانسیل خطی ناهمگن مرتبه‌ دوم با ضرایب غیرثابت را در نظر می‌گیریم که در آن توابع داده شده پیوسته هستند. در این مقاله پایداری هایرز-اولام این معادله را در فضای نرمدار ناارشمیدسی اعداد حقیقی ثابت می‌کنیم.
