Since 2006 the theory of slice hyperholomorphic functions and the related spectral theory on the S-spectrum have had a very fast development. This new spectral theory based on the S-spectrum has applications for example in the formulation of quaternionic quantum mechanics, in Schur analysis and in fractional diffusion problems. The notion of poly slice analytic function has been recently introduced for the quaternionic setting. In this paper we study the theory of poly slice monogenic functions and the associated functional calculus, called PS-functional calculus, which is the polyanalytic version of the S-functional calculus. Also for this poly monogenic functional calculus we use the notion of S-spectrum.
The sharp growth and distortion theorems are established for slice monogenic extensions of univalent functions on the unit disc $mathbb Dsubset mathbb C$ in the setting of Clifford algebras, based on a new convex combination identity. The analogous r
In this article, we first study, in the framework of operator theory, Pusz and Woronowiczs functional calculus for pairs of bounded positive operators on Hilbert spaces associated with a homogeneous two-variable function on $[0,infty)^2$. Our constru
We present an extension of some results of higher order calculus of variations and optimal control to generalized functions. The framework is the category of generalized smooth functions, which includes Schwartz distributions, while sharing many nonl
In this paper, two related types of dualities are investigated. The first is the duality between left-invertible operators and the second is the duality between Banach spaces of vector-valued analytic functions. We will examine a pair ($mathcal{B},Ps
We present an extension of the classical theory of calculus of variations to generalized functions. The framework is the category of generalized smooth functions, which includes Schwartz distributions while sharing many nonlinear properties with ordi
