Study of a Differential Operator of Heun Type Arising in Fluid Dynamics
The paper studies the non-selfadjoint linear differential operator Ly = d dt ( (1−acos t)y+bsin t dy dt ) acting in the Hilbert space L2(−π,π) that originated from a steady state stability problem in fluid dynamics. The operator L is of Heun type and involves two parameters a,b related to the hydrostatic pressure and capillary properties of the fluid. The results concern (1) the properties of f...
متن کاملHahn Difference Operator and Associated Jackson-Nörlund Integrals
This paper is devoted for a rigorous investigation of Hahn’s difference operator and the associated calculus. Hahn’s difference operator generalizes both the difference operator and Jackson’s q-difference operator. Unlike these two operators, the calculus associated with Hahn’s difference operator receives no attention. In particular, its right inverse has not been constructed before. We aim to...
متن کاملThe Hahn-Banach Theorem in Type Theory
We give the basic de nitions for pointfree functional analysis and present constructive proofs of the Alaoglu and Hahn Banach theorems in the set ting of formal topology Introduction We present the basic concepts and de nitions needed in a pointfree approach to functional analysis via formal topology Our main results are the constructive proofs of localic formulations of the Alaoglu and Helly H...
متن کاملA Theorem of the Hahn-banach Type for Linear Transformations
Every continuous linear functional defined on a vector subspace of a real normed space can be extended to the whole space so as to remain linear and continuous, and with the same norm(2). The extension of continuous linear transformations between two real normed spaces has been studied by several authors and for a long time it has been recognized that this problem has a close connection with th...
