### Scientific Posters

Authors will be asked to be present for questions and discussions during dedicated periods. Abstracts of the accepted posters will be available on the 7ECM website and the book of abstracts after the authors have confirmed their**participation**and paid the conference fee. Grant awardees get their tuition fee waived.

Authors of posters are encouraged to prepare their material thoroughly. Posters should present the main points of a mathematical work in a synthetic form that can be quickly grasped by other mathematicians. A poster should be displayed on some flat material, usually cardboard, of maximum A0 size, which is 84 cm (width) by 118 cm (height) - i.e. portrait format. Posters will be affixed to ad-hoc vertical panels.

Posters should be delivered to the conference office on the first day of the congress. Only posters of the authors present at the 7ECM will be displayed. Upon arrival at the Congress, registered participants presenting posters will receive information concerning the precise exhibition place and the time for presentation of their posters, when their presence is expected.

The Program Committee has accepted 83 poster abstracts. The Organizers are looking forward to welcoming all scientists who present posters.

All scientific posters can be found in the **scientific program**.
