The Cyclically Resolvable Steiner Triple Systems of Order 57

open access: yesMathematics
A resolution of a Steiner triple system of order v (STS(v)) is point-cyclic if it has an automorphism permuting the points in one cycle. An STS(v) is cyclically resolvable if it has at least one point-cyclic resolution. Cyclically resolvable STS(v)s have

Involutions of the Moduli Space of Principal E6-Bundles over a Compact Riemann Surface

open access: yesAxioms
In this paper, the fixed points of involutions on the moduli space of principal E6-bundles over a compact Riemann surface X are investigated. In particular, it is proved that the combined action of a representative σ of the outer involution of E6 with ...
