Algebraic reduction of one-loop Feynman graph amplitudes [PDF]

, 1999
An algorithm for the reduction of one-loop n-point tensor integrals to basic integrals is proposed. We transform tensor integrals to scalar integrals with shifted dimension and reduce these by recurrence relations to integrals in generic dimension.

Extending the Applicability of a Two-Step Chord-Type Method for Non-Differentiable Operators

Mathematics, 2019
The semi-local convergence analysis of a well defined and efficient two-step Chord-type method in Banach spaces is presented in this study. The recurrence relation technique is used under some weak assumptions.

Relativistic Kramers-Pasternack Recurrence Relations

, 2009
Recently we have evaluated the matrix elements $$,$ where $O$ $={1,\beta, i\mathbf{\alpha n}\beta} $ are the standard Dirac matrix operators and the angular brackets denote the quantum-mechanical average for the relativistic Coulomb problem, in terms of ...

On the Accessibility of Newton’s Method under a Hölder Condition on the First Derivative

Algorithms, 2015
We see how we can improve the accessibility of Newton’s method for approximating a solution of a nonlinear equation in Banach spaces when a center Hölder condition on the first derivative is used to prove its semi-local convergence.

Self-dual Koornwinder-Macdonald polynomials

, 1995
We prove certain duality properties and present recurrence relations for a four-parameter family of self-dual Koornwinder-Macdonald polynomials. The recurrence relations are used to verify Macdonald's normalization conjectures for these polynomials ...

Cognitive emotion regulation strategies in relation to treatment outcome in a clinical sample of adolescents with personality disorders

Clinical Psychology &Psychotherapy, Volume 29, Issue 6, Page 1897-1904, November/December 2022., 2022
Abstract The aim of this study was to examine cognitive emotion regulation strategies (CERS) of help‐seeking adolescents diagnosed with personality disorders. At pre‐treatment, patients (N = 116) were found to use some maladaptive but also some adaptive CERS more often than adolescents from the general population.

Identities in the spirit of Euler

Extracta Mathematicae, 2020
In this paper we develop new identities in the spirit of Euler. We shall investigate and report on new Euler identities of weight p + 2, for p an odd integer, but with a non unitary argument of the harmonic numbers.

On Jacobsthal and Jacobsthal-Lucas Hybrid Numbers

Annales Mathematicae Silesianae, 2019
The hybrid numbers are generalization of complex, hyperbolic and dual numbers. In this paper we consider special kinds of hybrid numbers, namely the Jacobsthal and the Jacobsthal-Lucas hybrid numbers and we give some their properties.

A structured reflection for improving third party interventions and mediation practice: Reconsidering debrief

Conflict Resolution Quarterly, Volume 40, Issue 2, Page 213-229, Winter 2022., 2022
Abstract We make a case for structured reflective practice for improving third‐party interventions and mediation decision‐making and outcomes. We propose that a lack of awareness of the automatic, intuitive nature of judgments that dominate the fast‐paced and uncertain mediation circumstances risk a proper treatment of implicit social‐psychological ...

Jacobsthal Representation Hybrinomials

Annales Mathematicae Silesianae, 2022
Jacobsthal numbers are a special case of numbers defined recursively by the second order linear relation and for these reasons they are also named as numbers of the Fibonacci type.
