A sharp discrete Sobolev inequality and left inverses of higher order differences

Raul Hindov, Shahaf Nitzan, Jan-Fredrik Olsen +1

For integers $α, d ⩾ 1$ , we determine the best constants in the inequalities $∣∣ (a_{j})_{j = 1}^{d} ∣ ∣_{ℓ^{1}} ⩽ C_{α, d} ∣∣ ((Δ^{α} a)_{j})_{j = 1}^{d + α} ∣ ∣_{ℓ^{2}},$ where $Δ$ i…

Diverse yet consistent: How mathematicians position computational thinking across research and teaching

Jan-Fredrik Olsen, Tor Ole B Odden, Elise Lockwood

Recent research in mathematics education points to an "epistemic clash" when programming and computational thinking (CT) are leveraged alongside more established forms of mathemati…

How Disciplinary Norms Influence Mathematicians' Views of Programming in Undergraduate Mathematics

Jan-Fredrik Olsen, Tor Ole B Odden

Programming is deeply embedded in contemporary mathematical practice, yet its epistemic status in university mathematics teaching remains contested. Little is known about how mathe…
