Integro-differential equations in Banach spaces and analytic resolving families of operators

open access: yesContemporary Mathematics. Fundamental Directions, 2023
We study a class of equations in Banach spaces with a Riemann–Liouville-type integro-differential operator with an operator-valued convolution kernel. The properties of \(k\)-resolving operators of such equations are studied and the class \(\mathcal A_{m,K,\chi}\) of linear closed operators is defined such that the belonging to this class is ...

Solvability of fractional differential inclusions with nonlocal initial conditions via resolvent family of operators [PDF]

open access: yesInternational Journal of Nonlinear Sciences and Numerical Simulation, 2020
Abstract In this paper, we consider mild solutions to fractional differential inclusions with nonlocal initial conditions. The main results are proved under conditions that (i) the multivalued term takes convex values with compactness of resolvent family of operators; (ii) the multivalued term takes nonconvex values with compactness of ...

DUALITY THEORY OF REGULARIZED RESOLVENT OPERATOR FAMILY

open access: yesJournal of Applied Analysis & Computation, 2011
Let \( k \in C(R^+)\), A be a closed linear densely defined operator in the Banach space \(X\) and \( \{R(t)\}_{t\geq 0} \) be an exponentially bounded \(k\)-regularized resolvent operator families generated by A. In this paper, we mainly study pseudo k-resolvent and duality theory of k-regularized resolvent operator families.

Inverse Problem for Evolutionary Equation with the Gerasimov – Caputo Fractional Derivative in the Sectorial Case

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2019
We investigates the unique solvability of a class of linear inverse problems with a time-independent unknown coefficient in an evolution equation in Banach space, which is resolved with respect to the fractional Gerasimov – Caputo derivative.

Threshold approximations with corrector for the resolvent of a factorized selfadjoint operator family [PDF]

open access: yesSt. Petersburg Mathematical Journal, 2006
In a Hilbert space we consider the family of operators admitting a factorization A(t) = X(t)∗X(t), where X(t) = X0 + tX1, t ∈ R. We suppose that the subspace N = KerA(0) is finite-dimensional. For the resolvent (A(t) + e2I)−1, we obtain an approximation in the operator norm on a fixed interval |t| ≤ t0 for small values of e. This approximation contains

Smooth quantum-classical transition in photon subtraction and addition processes [PDF]

open access: yes, 2009
Recently Parigi et al. [Science 317, 1890 (2007)] implemented experimentally the photon subtraction and addition processes from/to a light field in a conditional way, when the required operations were produced successfully only upon the positive outcome ...

Iterative Schemes for Finite Families of Maximal Monotone Operators Based on Resolvents

open access: yesAbstract and Applied Analysis, 2014
The purpose of this paper is to present two iterative schemes based on the relative resolvent and the generalized resolvent, respectively. And, it is shown that the iterative schemes converge weakly to common solutions for two finite families of maximal monotone operators in a real smooth and uniformly convex Banach space and one example is ...

Symmetries and entanglement features of inner-mode resolved correlations of interfering nonidentical photons [PDF]

open access: yes, 2018
Multiphoton quantum interference underpins fundamental tests of quantum mechanics and quantum technologies. Consequently, the detrimental effect of photon distinguishability in multiphoton interference experiments can be catastrophic.
