## Eran NevoInstitute of Mathematics, Hebrew University, Givat Ram, Jerusalem 91904, Israel. E-mail: nevo[at]math.huji.ac.il TL: +972-2-6586871 ## Current Teaching: Linear Algebra 2.## Research## Interests- Combinatorics - with connections to commutative algebra, topology, geometry and convexity.
## Projects- Face numbers and flag-face numbers of simplicial complexes (for example: spheres triangulations) and polytopes (for example: cubical polytopes).
Tools include for example: the Stanley-riesner ring, toric varieties, framework rigidity. - Betti tables of monomial ideals (for example: edge ideals) and related invariants (for example: regularity).
Topological tools are also available here via Hochster's formula. - Embeddability of simplicial complexes in manifolds.
Tools include for example: the van-Kampen obstruction and higher minor notions.
