Galois theory has such close analogies with the theory of coverings that algebraists use a geometric language to speak of field extensions, while topologists sp

Assuming little technical background, the author presents the strong analogies between these two concepts starting at an elementary level.

Graphs drawn on two-dimensional surfaces have always attracted researchers by their beauty and by the variety of difficult questions to which they give rise. Th
