Pseudo-differential operators have emerged as pivotal tools in modern analysis, generalising classical differential operators to encapsulate non-local behaviour via their symbol calculus. Their ...

Let G be a simply connected connected real nilpotent Lie group with Lie algebra g, H a connected closed subgroup of G with Lie algebra h and β ∈ h* satisfying β([h,h]) = {0}. Let χβ be the unitary ...

The talk is dedicated to self-adjoint differential operators in the case of infinite- dimensional coordinate spaces. In particular, it is considered the space of real- valued sequences. It is ...

With the exponential growth in demand for high-speed data transmission, the 5G system infrastructure, despite its impressive peak data rate of 10 gigabits per second, is increasingly inadequate for ...
