Explicit Solutions of Linear Discrete Delay Systems: A Comprehensive Survey of Delayed Matrix Functions and Their Applications

open access: yesAxioms
This survey provides a systematic review of delayed matrix functions and their role in deriving explicit solutions for linear discrete delay systems. Tracing the evolution from foundational single-delay first-order systems to sophisticated multi-delay ...

Integral representation of the solutions to Heun's biconfluent equation

open access: yesAbstract and Applied Analysis, 2004
First, we trace the genesis of the canonical form of Heun's biconfluent equation. Second, we present a method which allows us to find an integral expression as a solution to our equation, and finally, using the properties of Meijer G-functions, we give ...

A Representation for the Solution of Fredholm Integral Equations [PDF]

open access: yesProceedings of the American Mathematical Society, 1969
This paper provides a new representation formula for the solution of Fredholm integral equations of the second kind. The formula has certain computational advantages over the usual representation involving the resolvent or the representation formula of Krein.

An analog of the Cauchy formula for certain Beltrami equations

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2019
The Beltrami differential equations are intrinsic generalizations of the Cauchy–Riemann system in complex analysis. Their solutions generalize holomorphic functions. As known, solutions to many problems of the complex analysis are based on application of

Lax Representation and Darboux Solutions of the Classical Painlevé Second Equation

open access: yesAdvances in Mathematical Physics, 2021
In this article, we present Darboux solutions of the classical Painlevé second equation. We reexpress the classical Painlevé second Lax pair in new setting introducing gauge transformations to yield its Darboux expression in additive form. The new linear

Cup‐Like Nuclei Is a Hallmark of DUX4/ERG Acute Lymphoblastic Leukemia and Reveals Cytoplasmic Mitochondria Accumulation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Cup‐like nuclei are a distinctive morphological feature observed in certain cases of acute lymphoblastic leukemia (ALL). We provide evidence that they characterize DUX4/ERG ALL independently of IKZF1 deletion and reveal marked mitochondrial accumulation in this ALL subset.

Fundamental Solution of the Volkov Problem (Characteristic Representation) [PDF]

open access: yesJournal of Nonlinear Mathematical Physics, 1998
The characteristic representation, or Goursat problem, for the Klein-Fock-Gordon equation with Volkov interaction [1] is regarded. It is shown that in this representation the explicit form of the Volkov propagator can be obtained. Using the characteristic representation technique, the Schwinger integral [2] in the Volkov problem can be calculated.
