Student Perceptions of Tablet-Based Teaching and Learning in TNE Undergraduate Mathematics
Dimitrios Chiotis
Tablet-based teaching and learning has become increasingly common in university mathematics courses, offering capabilities such as digital ink, dynamic visualisation, and real-time…
A Metric Framework for Approximate Transitivity, Mixing, and Hypercyclicity
Hadi Obaid Alshammari, Otmane Benchiheb, Dimitrios Chiotis
We study metric versions of transitivity, mixing, and hypercyclicity for continuous maps, based on intersections of the form \( f^{n}(U)\cap B_δ(V)\neq\varnothing. \) We introduce…
Exterior powers and pointwise creation operators
Dimitrios Chiotis, Zinaida Lykova, N. J. Young
We develop a theory of pointwise wedge products of vector-valued functions on the circle and the disc, and obtain results which give rise to a new approach to the analysis of the m…
Exterior products of operators and superoptimal analytic approximation
Dimitrios Chiotis, Zinaida Lykova, Nicholas Young
We give a new algorithm for the construction of the unique superoptimal analytic approximant of a given continuous matrix-valued function on the unit circle, making use of exterior…
