The variational formula (1.1) is particularly useful for a upper bound of gap(L).

WebFeb 25, 2024 · In a strip, we consider an equation with the Euler–Poisson–Darboux operator containing a real positive parameter. We prove an energy inequality and the uniqueness of the classical solution of the Cauchy problem for the homogeneous equation, derive a formula for the solution, and establish its continuous dependence on the parameter. WebSep 2, 2024 · Abstract. We study infinite multiplicative Toeplitz matrices and Toeplitz operators on the Hardy space H^2 (\mathbb {T}^ {\infty}) over the infinite-dimensional polydisc. This pair is a companion to the pair of Toeplitz matrices and Toeplitz operators on the Hardy space over the unit disc.
