The Journal of Operator Theory endeavours to publish significant articles in all areas of operator theory, operator algebras and closely related domains. All accepted manuscripts are carefully ...
Dirac operators lie at the heart of both mathematical physics and differential geometry, offering a unifying framework for the treatment of quantum mechanical systems and geometrical invariants. Their ...
Yosra Barkaoui's doctoral dissertation in mathematics at the University of Vaasa, Finland, has successfully generalised a fundamental theorem that has ...
Fuglede-Putnam Theorem has been proved for a considerably large number of class of operators. In this paper by using the spectral theory, we obtain a theoretical and general framework from which ...
A classic math rule now handles infinity. New work strengthens the math behind physics and unbounded systems. % ...
Spectral problems in boundary value problems constitute a fundamental area of applied mathematics and mathematical physics, where the focus lies on determining eigenvalues and corresponding ...
