Birkhoff–James Orthogonality and Applications: A Survey
نویسندگان
چکیده
In the last few decades, concept of Birkhoff–James orthogonality has been used in several applications. this survey article, results known on necessary and sufficient conditions for certain Banach spaces are mentioned. Their applications studying geometry normed given. The connections between orthogonality, Gateaux derivative subdifferential set norm function provided. Several interesting distance formulas can be obtained using characterizations which also end, some new obtained.

متن کاملMultiple Orthogonality and Applications in Numerical Integration
In this paper a brief survey of multiple orthogonal polynomials defined using orthogonality conditions spread out over r different measures are given. We consider multiple orthogonal polynomials on the real line, as well as on the unit semicircle in the complex plane. Such polynomials satisfy a linear recurrence relation of order r+1, which is a generalization of the well known three-term recur...
متن کاملA characterization of orthogonality preserving operators
In this paper, we characterize the class of orthogonality preserving operators on an infinite-dimensional Hilbert space $H$ as scalar multiples of unitary operators between $H$ and some closed subspaces of $H$. We show that any circle (centered at the origin) is the spectrum of an orthogonality preserving operator. Also, we prove that every compact normal operator is a strongly orthogo...
