The SOS Rank of Biquadratic Forms
In 1973, Calderón proved that an $m \times 2$ positive semidefinite (psd) biquadratic form can always be expressed as the sum of squares (sos) of ${3m(m+1) \over 2}$ quadratic forms. Very recently, by applying Hilbert's theorem, we proved that a $2 \times 2$ psd biquadratic form can always be expressed as the sum of squares of three quadratic forms. This improved Calderón's result for $m=2$, and left the sos rank problem of $m \times 2$ biquadratic forms for $m \ge 3$ to further exploration. …

In the United States, the power to use military force, including ordering airstrikes, is not granted explicitly to the President in the U.S. Constitution. Rather, this authority comes from Congress's power to declare war and grant the President the authority to take military action under Article II, Section 2 of the Constitution. This authority is further developed through the War Powers Resolution of 1973, which places limits on the President's ability to deploy U.S. forces into hos…

Short monochromatic odd cycles
It is easy to see that every $k$-edge-colouring of the complete graph on $2^k+1$ vertices contains a monochromatic odd cycle. In 1973, Erdős and Graham asked to estimate the smallest $L(k)$ such that every $k$-edge-colouring of $K_{2^k+1}$ contains a monochromatic odd cycle of length at most $L(k)$. Recently, Girão and Hunter obtained the first nontrivial upper bound by showing that $L(k)=O(\frac{2^k}{k^{1-o(1)}})$, which improves the trivial bound by a polynomial factor. We obtain an exponen…

Hamilton cycles in tough $(2P_2 \cup P_1)$-free graphs

Hamilton cycles in tough $(2P_2 \cup P_1)$-free graphs
In 1973, Chvátal conjectured that there exists a constant $t_0$ such that every $t_0$-tough graph on at least three vertices is Hamiltonian. While this conjecture is still open, work has been done to confirm it for several graph classes, including all $F$-free graphs for every 5-vertex linear forest $F$ other than $P_5$ and $2P_2\cup P_1$. In this note, we show that 11-tough $(2P_2 \cup P_1)$-free graphs on at least three vertices are Hamiltonian.

Simpler and Faster Contiguous Art Gallery
The contiguous art gallery problem was introduced at SoCG'25 in a merged paper that combined three simultaneous results, each achieving a polynomial-time algorithm for the problem. This problem is a variant of the classical art gallery problem, first introduced by Klee in 1973. In the contiguous art gallery problem, we are given a polygon P and asked to determine the minimum number of guards needed, where each guard is assigned a contiguous portion of the boundary of P that it can see, such tha…

A universal extension of helicity to topological flows
Helicity is a fundamental conserved quantity in physical systems governed by vector fields whose evolution is described by volume-preserving transformations on a three-manifold. Notable examples include inviscid, incompressible fluid flows, modeled by the three-dimensional Euler equations, and conducting plasmas, described by the magnetohydrodynamics (MHD) equations. A key property of helicity is its invariance under volume-preserving diffeomorphisms. In an influential article from 1973, Arnold…

A Structural Linear-Time Algorithm for Computing the Tutte Decomposition
The block-cut tree decomposes a connected graph along its cutvertices, displaying its 2-connected components. The Tutte-decomposition extends this idea to 2-separators in 2-connected graphs, yielding a canonical tree-decomposition that decomposes the graph into its triconnected components. In 1973, Hopcroft and Tarjan introduced a linear-time algorithm to compute the Tutte-decomposition. Cunningham and Edmonds later established a structural characterization of the Tutte-decomposition via totall…

Variational Construction of Homoclinic and Heteroclinic Orbits in the Planar Sitnikov Problem
The Sitnikov problem is a special case of the three-body problem. The system is known to be chaotic and has been studied by symbolic dynamics (J. Moser, Stable and random motions in dynamical systems, Princeton University Press, 1973). We study the limiting case of the Sitnikov problem as the eccentricity of the massive particles tends to 1. By variational method, we show the existence of infinitely many homoclinic and heteroclinic solutions in the planar Sitnikov problem. In a previous work, f…

The Brown-Erdős-Sós conjecture in dense triple systems
The famous Brown-Erdős-Sós conjecture from 1973 states, in an equivalent form, that for any fixed $δ>0$ and integer $k\geq 3$ every sufficiently large linear $3$-uniform hypergraph of size $δn^2$ contains some $k$ edges spanning at most $k+3$ vertices. We prove it to hold for $δ>4/5$, establishing the first bound of this kind.

On the construction of a counterexample to Strassen's rank additivity conjecture
The rank additivity conjecture, first formulated by Volker Strassen in 1973, states that the rank of the direct sum of two independent tensors is equal to the sum of their individual ranks. In the last decades, this conjecture has been a central topic in tensor rank theory and its implications for computational complexity. In 2019, Yaroslav Shitov disproved this conjecture in its general form by showing the existence of a counter-example using a dimension counting argument. In this paper, we pr…

Model-Free Deep Hedging with Transaction Costs and Light Data Requirements
Option pricing theory, such as the Black and Scholes (1973) model, provides an explicit solution to construct a strategy that perfectly hedges an option in a continuous-time setting. In practice, however, trading occurs in discrete time and often involves transaction costs, making the direct application of continuous-time solutions potentially suboptimal. Previous studies, such as those by Buehler et al. (2018), Buehler et al. (2019) and Cao et al. (2019), have shown that deep learning or reinf…

The average undergrad tuition fee in the 1974/75 academic year in Canada, across all disciplines, was $547 ($3445 adjusted to 2025)
Fees 50 years later in 2024/25 were $7360 ($7496 adjusted)
That is more than double. 117%.
And I *know* from personal experience this is a low ball average. If I could find a breakdown by discipline or by length of study for today, some would be even more obscene.
What has changed? Any occupation outside a minimum wage paying job demands a 2-4yr undergraduate diploma or degree, if not more.
Think about the 1970s and how common it was for people to get good paying jobs, leading to careers, without even high school education. Our free education stops with high school.
My family is a good example.
Mom and Step Dad: teacher college/degree. One got a Masters mid career.
Dad: didn’t complete HS
Father in law: didn’t complete HS
Mother in law: completed HS mid-career
Leadership positions and full careers demand a Masters or PhD requiring 5-10 years of study after HS!
Add in the cost of food and housing and the massive cuts happening at all colleges and universities because of the loss of international student tuition and I am going to go out on a limb and say our students today are going to pay double the price for a far worse experience than possibly any time since the Second World War.
Public education should be free.
Food and Housing should be controlled.
If the only thing government cares about is the economy, then they are setting us up for failure, and have been for decades.
(Don’t get me started on the kinds of “values” Canadian governments demonstrate when International student tuitions are 5x more than domestic students, let alone the inherent revenue risk in that funding strategy that has now come home to roost)

Some Turán-type results for signless Laplacian spectral radius
Half a century ago, Bollobás and Erdős [Bull. London Math. Soc. 5 (1973)] proved that every $n$-vertex graph $G$ with $e(G)\ge (1- \frac{1}{k} + \varepsilon )\frac{n^2}{2}$ edges contains a blowup $K_{k+1}[t]$ with $t=Ω_{k,\varepsilon}(\log n)$. A well-known theorem of Nikiforov [Combin. Probab. Comput. 18 (3) (2009)] asserts that if $G$ is an $n$-vertex graph with adjacency spectral radius $λ(G)\ge (1- \frac{1}{k} + \varepsilon)n$, then $G$ contains a blowup $K_{k+1}[t]$ with $t=Ω_{k,\var…

Let $f^{(r)}(n;s,k)$ be the maximum number of edges in an $n$-vertex $r$-uniform hypergraph containing no $k$ edges on at most $s$ vertices. Brown, Erdős and Sós conjectured in 1973 that the limit $\lim_{n\rightarrow \infty}n^{-2}f^{(3)}(n;k+2,k)$ exists for all $k$. Recently, Delcourt and Postle settled the conjecture and their approach was generalised by Shangguan to every uniformity $r\ge 4$: the limit $\lim_{n\rightarrow \infty}n^{-2}f^{(r)}(n;rk-2k+2,k)$ exists for all $r\ge 3$ and $k\ge…
