Liaison, Schottky Problem and Invariant Theory

This volume is a homage to the memory of the Spanish mathematician Federico Gaeta (1923-2007). It offers a historical presentation of his life and presents surveys and original research papers on the mathematics he studied.

Federico Gaeta (19232007) was a Spanish algebraic geometer who was a student of Severi. He is considered to be one of the founders of linkage theory, on which he published several key papers. After many years abroad he came back to Spain in the 1980s. He spent his last period as a professor at Universidad Complutense de Madrid. In gratitude to him, some of his personal and mathematically close persons during this last station, all of whom bene?ted in one way or another by his ins- ration, have joined to edit this volume to keep his memory alive. We o?er in it surveys and original articles on the three main subjects of Gaeta's interest through his mathematical life. The volume opens with a personal semblance by Ignacio Sols and a historical presentation by Ciro Ciliberto of Gaeta's Italian period. Then it is divided into three parts, each of them devoted to a speci?c subject studied by Gaeta and coordinated by one of the editors. For each part, we had the advice of another colleague of Federico linked to that particular subject, who also contributed with a short survey. The ?rst part, coordinated by E. Arrondo with the advice of R.M.

Linkage theory is revisited with a survey and several original research papers There is a survey and two original research papers on Schottky problem An unpublished article of Federico Gaeta is included in the book A historical presentation of the interaction of Gaeta with the classical Italian school of algebraic geometry is also included in the book Includes supplementary material: sn.pub/extras
