Let X be a degree d curve in the projective space P^r.&nbsp;A general hyperplane H intersects X at d distinct points; varying H defines a monodromy&nbsp;action on X∩H. The resulting permutation group G is the sectional monodromy group of X.&nbsp;When the ground field has characteristic zero the group G is known to be the full symmetric group.By work of Harris, if G contains the alternating group, then X satisfies a strengthened Castelnuovo's inequality&nbsp;(relating the degree and the genus of X).The talk is concerned with sectional monodromy groups in positive characteristic.&nbsp;I will describe all nonstrange nondegenerate curves in projective spaces of dimension r>2.&nbsp;for which G is not symmetric or alternating. For a particular family of plane curves.&nbsp;I will compute the sectional monodromy groups and thus answer an old question on Galois groups of generic trinomials.
