We provide $ forallexists $-axiom systems for two variants of plane equiaffine geometry, one whose automorphisms are area preserving affinities, the other whose automorphisms are oriented area preserving affinities. The axiom systems are formulated in first order languages with points as the only ...

As such, quasiconformal maps are considerably more plentiful than conformal maps, and in particular it is possible to create piecewise smooth quasiconformal maps by gluing together various simple maps such as affine maps or Möbius transformations; such piecewise maps will naturally arise when trying ...
for medium-sized and large , where is the von Mangoldt function; we also consider variants of this sum in which one of the von Mangoldt functions is replaced with a (higher order) divisor function, but for sake of discussion let us focus just on the sum (1). Understanding this sum is...
The second mode called Structure, represent protein as ‘residue gas,’ where every amino acid is represented as a triangle, build from the N-Cα-C atoms that are displaced and rotated in space (affine matrices), and further refined with geometry-aware attention operation termed ‘invariant ...
In algebraic geometry, we can use the concept of an affine space as a model for understanding the world around us. An affine space is a set of points that are related by rational functions. This means that these points are connected to one another in terms of distance or angle....
What are the differences among expressions, equations, and functions? How do you prove the divisibility of a monomial? What is an affine function? Explain why polynomials can't have negative exponents. What is understood by the term degree of a polynomial? Why is convolution equal to polynomial...
it is all polynomials vanishing at the origin modulo those,vanishing to degree higher than one. Taylor's theorem shows this makes sense also for smooth functions. Then to globalize this concept, consider the injection of X into XxX as the diagonal, where X is some manifold, or affine space...
Another related analogy between Euclidean and Minkowskian geometry is the decomposition of a timelike 4-vector into components relative to a Minkowski coordinate system, e.g. for particle 4-momentum where is a unit 3-vector parallel to 3-velocity, , , and . This is the Minkowskian equivalent...
