Let $\mathbf{A}$ and $\mathbf{B}$ be non-bipartite loopless undirected graphs such that $\mathbf{A}\to\mathbf{B}$. The Brakensiek–Guruswami conjecture asserts that … is…

Let $\mathbf{1in3}$ and $\mathbf{\check{C}^+}$ be the finite relational templates used in the paper, with a homomorphism $\mathbf{1in3}\to\mathbf{\check{C}^+}$. The associated prom…

For integers $2\leq k<l$, let $\mathbf{LO}_k$ and $\mathbf{LO}_l$ denote the corresponding symmetric relational templates, and let $\mathrm{PCSP}(\mathbf{LO}_k,\mathbf{LO}_l)$ be t…
