On the q-exponential of matrix q-Lie algebras
Special Matrices, 2017 In this paper, we define several new concepts in the borderline between linear algebra, Lie groups and q-calculus.We first introduce the ring epimorphism r, the set of all inversions of the basis q, and then the important q-determinant and corresponding ...

Data-Driven Learning of Q-Matrix. [PDF]
Appl Psychol Meas, 2012 The recent surge of interests in cognitive assessment has led to developments of novel statistical models for diagnostic classification. Central to many such models is the well-known Q-matrix, which specifies the item–attribute relationships.

Modelling and analysis of equivalent SISO d-q impedance of grid-connected converters
, 2021 Small-signal stability of three-phase grid-connected converters can be analysed by using the impedance-based method in d-q frame. Based on this approach, the d-q impedance models of both source and load subsystems are represented with 2-by-2 matrices ...

Factorizations for q-Pascal matrices of two variables
Special Matrices, 2015 In this second article on q-Pascal matrices, we show how the previous factorizations by the summation matrices and the so-called q-unit matrices extend in a natural way to produce q-analogues of Pascal matrices of two variables by Z. Zhang and M.

Improved Performance of Model Fit Indices with Small Sample Sizes in Cognitive Diagnostic Models
International Journal of Assessment Tools in Education, 2019 Selecting an appropriate cognitive diagnostic model (CDM) for data analysis is always challenging. Studies have explored several model fit indices for CDMs.

The Panorama of Spin Matrix theory
Journal of High Energy Physics, 2023 Spin Matrix theory describes near-BPS limits of N $$ \mathcal{N} $$ = 4 SYM theory, which enables us to probe finite N effects like D-branes and black hole physics.

q-Riordan array for q-Pascal matrix and its inverse matrix [PDF]
, 2016 In this paper, we prove the q-analogue of the fundamental theorem of Riordan arrays. In particular, by defining two new binary operations {*}(q) and {*}(1/q), we obtain a q-analogue of the Riordan representation of the q-Pascal matrix.
