On the existence and uniqueness of
Lars Vlasveld
1 Applied Mathematics & Data Science, Amsterdam
Abstract. We introduce Lars (Figure 1), a student of applied mathematics and data science based in
Amsterdam. Existence is established by observation; uniqueness is assumed without proof.
Several open problems are stated in §3.
Keywords: geometry, linear algebra, machine learning, dusk at the beach
1 Definition
Definition 1.1 (Lars). Let L denote the element satisfying all of the following:
(i)L ∈ Amsterdam;
(ii)deg(L) → B.Sc. in Applied Mathematics & Data Science, convergence in progress;
(iii)interests(L) ⊇ {geometry, linear algebra, machine learning};
(iv)L is bounded, but not yet closed.
Remark 1.2. The subject is happiest when a mess turns out to have clean structure underneath: a proof, a dataset, a page layout.
2 A typical week, approximately normal
Weekly time allocation is well modelled by a Gaussian centred on coursework, with heavy tails.
3 Open problems
No completed works are claimed at time of writing. The following conjectures are offered instead, in increasing order of difficulty.
3.1Build something worth a §4.
3.2Finish the degree in finite time.
3.3Settle, once and for all, whether the triangle is really the strongest shape.
Progress on any of the above will be reported in a future revision of this page.
4 A moving part
A Lissajous figure: x(t) = sin(at + π/2) traced against y(t) = sin(bt). Pick the ratio.
