Tableaux and orbit harmonics quotients for finite transformation monoids
Mihalis Maliakas, Dimitra-Dionysia Stergiopoulou
We extend Grood's tableau construction of irreducible representations of the rook monoid and Steinberg's analogous result for the full transformation monoid. Our approach is charac…
Gorenstein versions of type groups and some Gcd-cd, Ghd-hd coincidences
Rudradip Biswas, Dimitra-Dionysia Stergiopoulou
In this short note, we characterise some Gorenstein versions of the concept of a group being of type as introduced by Olympia Talelli. And, we also generalize a different Talel…
Total trades, intersection matrices and Specht modules
Mihalis Maliakas, Dimitra-Dionysia Stergiopoulou
Trades are important objects in combinatorial design theory that may be realized as certain elements of kernels of inclusion matrices. Total trades were introduced recently by Ghor…
Gorenstein analogues of a projectivity criterion over group algebras
Rudradip Biswas, Dimitra-Dionysia Stergiopoulou
We formulate and answer Gorenstein projective, flat, and injective analogues of a classical projectivity question for group rings under some mild additional assumptions. Although t…
