Maqolada turli qalinlikdagi chegaraviy qatlamlarga ega statsionar singulyar qo’zg’algan chegaraviy masalalar uchun spektral-to’r usuli taklif qilinadi. Soha qatlamlarga moslashtirilgan elementlarga bo’linadi, har bir elementda yechim Chebyshev ko’phadlari bilan yaqinlashtiriladi. Sonli tajribalar usulning ε parametrga nisbatan tekis va eksponensial yaqinlashishini ko’rsatadi
