Generalized degree-power star conjecture for t-intersecting families

Less than 1 year old · traced to

Let 1≤t≤k1\leq t\leq k, 1≤r≤k−11\leq r\leq k-1, and let p≥2p\geq2 be real. Suppose that

n≥(t+1)(k−t+1).n\geq(t+1)(k-t+1).

If F⊆([n]k)\mathcal F\subseteq\binom{[n]}k is tt-intersecting, then, for every T∈([n]t)T\in\binom{[n]}t, define ℓr,p(F)\ell_{r,p}(\mathcal F) as the degree-power quantity used in the paper. Generalized degree-power star conjecture.

ℓr,p(F)≤ℓr,p(ST).\ell_{r,p}(\mathcal F)\leq\ell_{r,p}(\mathcal S_T).

This conjecture simultaneously extends the cases r=k−1r=k-1 and t=1t=1, established in the paper. Its parameter range is the sharp classical star range associated with Wilson's theorem and the Ahlswede--Khachatrian complete intersection theorem; the restriction p≥2p\geq2 is essential, as the paper gives a counterexample for 1<p<21<p<2.
