Abstract

This work presents problems of constructing finite-difference formulas in the Hilbert space, i.e., setting problems of constructing finite-difference formulas using functional methods. The work presents a functional statement of the problem of optimizing finite-difference formulas in the space W2(m,m1)(0,1)W_{2}^{\left(m,m-1\right)} \left(0,1\right). Here, representations of optimal coefficients of explicit finite-difference formulas of the Adams type on classes W2(m,m1)(0,1)W_{2}^{\left(m,m-1\right)} \left(0,1\right) for any m3m\ge 3 will be found.
