Shifting Operators in Geometric Quantization [PDF]
The original Bohr-Sommerfeld theory of quantization did not give operators of transitions between quantum quantum states. This paper derives these operators, using the first principles of geometric quantization.

In this paper, we study the common diskcyclic vectors for a path of diskcyclic operators. In particular, if is a path of diskcyclic operators, we show that under certain conditions the intersection of diskcyclic vectors for theses operators is a dense ...

Dynamics of shift operators on non-metrizable sequence spaces [PDF]
We investigate dynamical properties such as topological transitivity, (sequential) hypercyclicity, and chaos for backward shift operators associated to a Schauder basis on LF-spaces.

Otologic symptoms and hearing thresholds among a cohort of call center operators in Lagos
Background The call center operation jobs are becoming a global phenomenon. The use of headphones for 7 to 9 h daily with varying noise level exposure is quite common among call center operators. This can cause structural and/or functional changes in the

Shift operators, residue families and degenerate Laplacians [PDF]
We introduce new aspects in conformal geometry of some very natural second-order differential operators. These operators are termed shift operators.

AdS weight shifting operators [PDF]
AbstractWe construct a new class of differential operators that naturally act on AdS harmonic functions. These are weight shifting operators that change the spin and dimension of AdS representations. Together with CFT weight shifting operators, the new operators obey crossing equations that relate distinct representations of the conformal group.

We study the maximal operator $M_{\gamma}$ and the singular integral operator $A_{\gamma}$, associated with the generalized shift operator. The generalized shift operators are associated with the Laplace-Bessel differential operator.

Topological Transitivity of Shift Similar Operators on Nonseparable Hilbert Spaces
In this paper, we investigate topological transitivity of operators on nonseparable Hilbert spaces which are similar to backward weighted shifts.

A Functional Abstraction of Typed Invocation Contexts [PDF]
In their paper "A Functional Abstraction of Typed Contexts", Danvy and Filinski show how to derive a monomorphic type system of the shift and reset operators from a CPS semantics.

Hypercyclicity of adjoint of convex weighted shift and multiplication operators on Hilbert spaces [PDF]
A bounded linear operator $T$ on a Hilbert space $\mathfrak{H}$ is convex, if $$\|\mathfrak{T}^{2}v\|^2-2\|\mathfrak{T}v\|^2+\|v\|^2 \geq 0.$$ In this paper, sufficient conditions to hypercyclicity of adjoint of unilateral (bilateral) forward (backward ...
