Simon VIALARET

I am currently doing a PhD (2021-2025) under the supervision of Rémi Leclercq and Alberto Abbondandolo.

Research interests

I am interested in different aspects of the dynamics of Reeb flows in contact geometry, including the existence of systolic inequalities for diverse classes of contact forms.

Publications

Preprints (submitted)

• Systolic inequalities for S1-invariant contact forms in dimension three (arXiv)
• Sharp systolic inequalities for invariant tight contact forms on principal S1-bundles over S2 (arXiv)
