Conformally equivariant quantization: existence and uniqueness [PDF]
Annales de l'Institut Fourier, 1999 We prove the existence and the uniqueness of a conformally equivariant symbol calculus and quantization on any conformally flat pseudo-riemannian manifold (M,g). In other words, we establish a canonical isomorphism between the spaces of polynomials on T * M and of differential operators on tensor densities over M, both viewed as modules over the Lie ...

Existence and uniqueness of Bowen–York trumpets [PDF]
Classical and Quantum Gravity, 2011 We prove the existence of initial data sets which possess an asymptotically flat and an asymptotically cylindrical end. Such geometries are known as trumpets in the community of numerical relativists.

Straightening: existence, uniqueness and stability [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2014 One of the least studied universal deformations of incompressible nonlinear elasticity, namely the straightening of a sector of a circular cylinder into a rectangular block, is revisited here and, in particular, issues of existence and stability are addressed.

Existence and uniqueness for a semilinear sixth-order ODE
Electronic Journal of Qualitative Theory of Differential Equations, 2022 By using variational methods and maximum principles we discuss the existence, uniqueness and multiplicity of solutions for a semilinear sixth-order ODE. The main difference between our work and other related papers is that we treat a general case and we

Engineering Proceedings, 2023 In this paper, we investigate a fractional-order predator–prey model incorporating prey harvesting. In a non-delayed model, the Crowley–Martin functional response is studied. We first prove the existence, uniqueness, non-negativity and boundedness of the

A Malaria Status Model: The Perspective of Mittag-Leffler Function with Stochastic Component
Communication in Biomathematical Sciences, 2022 Malaria continues to affect many individuals irrespective of the status or class particularly in Sub-Saharan Africa. In this work, an existing malaria status classical model is studied in fractionalized perspective.

Fractional stochastic modelling of monkeypox dynamics
Results in Control and Optimization, 2023 Monkeypox virus is primarily transferred to humans via wild animals including rodents and more often the transmission ensues between humans to humans. This disease has been neglected in the past and little effort has been made by research to study the ...

Dynamic Multiagent Incentive Contracts: Existence, Uniqueness, and Implementation
Mathematics, 2020 Multiagent incentive contracts are advanced techniques for solving decentralized decision-making problems with asymmetric information. The principal designs contracts aiming to incentivize non-cooperating agents to act in his or her interest.
