Age Group Sensitivity Analysis of Epidemic Models: Investigating the Impact of Contact Matrix Structure
Zsolt Vizi, Evans Kiptoo Korir, Norbert Bogya +3
Understanding the role of different age groups in disease transmission is crucial for designing effective intervention strategies. A key parameter in age-structured epidemic models…
Towards solving the 7-in-a-row game
Domonkos Czifra, Endre Csóka, Zsolt Zombori +1
Our paper explores the game theoretic value of the 7-in-a-row game. We reduce the problem to solving a finite board game, which we target using Proof Number Search. We present a nu…
Swing lattice game and a short proof of the swing lemma for planar semimodular lattices
Gábor Czédli, Géza Makay
The swing lemma, due to G. Grätzer for slim semimodular lattices and extended by G. Czédli and G. Grätzer for all planar semimodular lattices, describes the congruence generated by…
Invariance groups of finite functions and orbit equivalence of permutation groups
Eszter K. Horváth, Géza Makay, Reinhard Pöschel +1
Which subgroups of the symmetric group S_n arise as invariance groups of n-variable functions defined on a k-element domain? It appears that the higher the difference n-k, the more…
