Finite rigid sets in curve complexes of nonorientable surfaces

The research article “Finite rigid sets in curve complexes of nonorientable surfaces”, co-authored by METU member Prof. Mustafa Korkmaz, has been published in Geometriae Dedicata.

A rigid set in a curve complex of a surface is a subcomplex such that every locally injective simplicial map from the set into the curve complex is induced by a homeomorphism of the surface. In this paper, we find finite rigid sets in the curve complexes of connected nonorientable surfaces of genus g with n holes for g+ n≠ 4.

Nonlocal hydrodynamic type of equations

The research article “Nonlocal hydrodynamic type of equations”, co-authored by METU member Assoc. Prof. Kostyantyn Zheltukhin, has been published in Communications in Nonlinear Science and Numerical Simulation.

We show that the integrable equations of hydrodynamic type admit nonlocal reductions. We first construct such reductions for a general Lax equation and then give several examples. The reduced nonlocal equations are of hydrodynamic type and integrable. They admit Lax representations and hence possess infinitely many conserved quantities.
