The theory of motifs: unified cohomology

by

Contemporary research in mathematics is engaged in unveiling the deepest foundations that unite arithmetic, geometry, and topology. At the heart of this quest, motif theory stands out as an ambitious answer, aiming to decipher a universal language behind the diversity of cohomological invariants arising from algebraic varieties. This perspective, sketched by Grothendieck in the mid-1960s, … Read more

Algebraic geometry: varieties and schemes

by

Algebraic geometry imposes itself as a fundamental pillar of modern mathematics, linking the study of polynomial equations to the deep geometric structure of their solution sets. It transcends pure analysis to offer a powerful language capable of addressing very abstract spaces from the perspective of topology, algebra, and geometry. Understanding algebraic varieties and schemes, which … Read more
