Liu, Xuefeng Explicit eigenvalue bounds of differential operators defined by symmetric positive semi-definite bilinear forms. (English) Zbl 1433.65054 J. Comput. Appl. Math. 371, Article ID 112666, 7 p. (2020). Summary: Recently, the eigenvalue problems formulated with symmetric positive definite bilinear forms have been well investigated with the aim of explicit bounds for the eigenvalues. In this paper, the existing theorems for bounding eigenvalues are further extended to deal with the case of eigenvalue problems defined by positive semi-definite bilinear forms. As an application, the eigenvalue estimation theorems are applied to the error constant estimation for polynomial projections.
