Tóm tắt

Trong bài báo này, tác giả thiết lập một số công thức tiệm cận và các bất đẳng thức hai bên cho tỉ lệ của hàm gamma theo hàm digamma. Xem xét ứng dụng của hàm gamma vào các hệ số Bernoulli trung tâm, tác giả đưa ra một số xấp xỉ tốt hơn và các bất đẳng thức hai bên của các hệ số Bernoulli trung tâm. Cuối cùng, để minh chứng cho sự vượt trội của các kết quả của chúng tôi, một số phép tính số được trình bày.
