Representations of the Quantum Algebra su_q(1,1) and Discrete q-Ultraspherical Polynomials
We derive orthogonality relations for discrete q-ultraspherical polynomials
and their duals by means of operators of representations of the quantum algebra
su_q(1,1). Spectra and eigenfunctions of these operators are found explicitly.
These eigenfunctions, when normalized, form an orthonormal basis in the
representation space.Comment: Published in SIGMA (Symmetry, Integrability and Geometry: Methods and

Degenerate Series Representations of the -Deformed Algebra
The q-deformed algebra is a real form of the q-deformed
algebra , , which differs from the quantum
algebra of Drinfeld and Jimbo. We study
representations of the most degenerate series of the algebra . The formulas of action of operators of these representations upon
the basis corresponding to restriction of representations onto the subalgebra
are given. Most of these representations
are irreducible. Reducible representations appear under some conditions for the
parameters determining the representations. All irreducible constituents which
appear in reducible representations of the degenerate series are found. All
-representations of are separated in the set of
irreducible representations obtained in the paper.Comment: Published in SIGMA (Symmetry, Integrability and Geometry: Methods and

INTERNATIONAL FINANCIAL REPORTING STANDARD (IFRS) WILL SUPPORT MANAGEMNET ACCOUNTING SYSTEM FOR SMALL AND MEDIUM ENTREPRISE (SME)?"
The problem of reporting financial data useful for readers in most of the countries andlanguages is receiving considerable attention with the implementation of the new financialreporting standards in the United States, Canada, Australia, Europe and Japan. The theoreticalmodel of the new standard forms that would be produced in a particular country and especially forpublic and world companies will expedite the search and analyses of usefulness of this reporting.The characteristic formulation of IFRS is implemented to obtain a common language in reportingfinancial data, capable to be interpreted by readers in the same meaning. There are a lot ofinterferences, convergences and divergences between accounting and financial reporting that stillshould be resolved for SMEs. Using a comparative method between management accounting in twocountries, Canada and Romania, it will be enable to show how IFRS can solve some of thosedifferences.IFRS ,Management Accounting. SWOT
Measuring reasoning capabilities of ChatGPT
I shall quantify the logical faults generated by ChatGPT when applied to
reasoning tasks. For experiments, I use the 144 puzzles from the library
\url{https://users.utcluj.ro/~agroza/puzzles/maloga}~\cite{groza:fol}. The
library contains puzzles of various types, including arithmetic puzzles,
logical equations, Sudoku-like puzzles, zebra-like puzzles, truth-telling
puzzles, grid puzzles, strange numbers, or self-reference puzzles. The correct
solutions for these puzzles were checked using the theorem prover
Prover9~\cite{mccune2005release} and the finite models finder
Mace4~\cite{mccune2003mace4} based on human-modelling in Equational First Order
Logic. A first output of this study is the benchmark of 100 logical puzzles.
For this dataset ChatGPT provided both correct answer and justification for 7\%
only. %, while BARD for 5\%. Since the dataset seems challenging, the
researchers are invited to test the dataset on more advanced or tuned models
than ChatGPT3.5 with more crafted prompts. A second output is the
classification of reasoning faults conveyed by ChatGPT. This classification
forms a basis for a taxonomy of reasoning faults generated by large language
models. I have identified 67 such logical faults, among which: inconsistencies,
implication does not hold, unsupported claim, lack of commonsense, wrong
justification. The 100 solutions generated by ChatGPT contain 698 logical
faults. That is on average, 7 fallacies for each reasoning task. A third ouput
is the annotated answers of the ChatGPT with the corresponding logical faults.
Each wrong statement within the ChatGPT answer was manually annotated, aiming
to quantify the amount of faulty text generated by the language model. On
average, 26.03\% from the generated text was a logical fault
