Dear Colleagues,

You are most cordially invited to the seminar organized by the Department of Mathematics.

**Title:** $\omega$-Weighted Digraphs and Local Complementations

**Speaker:** Aslı Güçlükan İlhan (Dokuz Eylül University)

**Abstract:** In this talk, we introduce $\omega$-weighted digraphs for a given dimension function $\omega$. We generalize the notion of a local complementation to $\omega$-weighted digraphs. Then we establish a bijection between isomorphism classes of $\omega$-weighted digraphs up to local complementations and the isomorphism classes of weakly $\mathbb{Z}_2^n$-equivariant small covers over a product of simplices.
