Does it still have a sense of Euclid-style geometry-are there still cubes and spheres, so to speak? Is it mostly about 1D curves/2D surfaces, or does it consider higher dimensions? Are the surfaces which the field concerns mostly graphs of several variables, e.g. ## x^3+y^3+z^3=1 ##, or are they more abstract, like in topology? What prerequisites does it have? Are complex numbers/complex analysis used at all?(adsbygoogle = window.adsbygoogle || []).push({});
