The conic h(x, y) = [x.sup.2] + [cy.sup.2] -1 = 0, c [member of] R, is an invariant algebraic curve
of system (1).
The following examples explain how for the reader who is not familiar with the concepts of algebraic function fields (i.e., algebraic curves
) as genus, rational points etc is referred to .
5.1 General position with respect to algebraic curves
For example, Bezout's theorem, that the number of points of intersection of two algebraic curves
is equal to the product of their degrees, would obviously suffer greatly if restricted to the real affine plane."
Although we have presented an algorithm to compute singular points of irreducible algebraic curves
in , the algorithm is almost experimental and related analysis of the algorithm is not provided, for instance, the feasibility and complexity.

Via the correspondence between algebraic curves
and floor diagrams [BM09, Theorem 2.5] these notions correspond literally to the respective analogues for algebraic curves
A selection of 10 papers from it consider such topics as self-dual codes and invariant theory; vector bundles in error-correcting for geometric Goppa codes; combinatorial designs and code synchronization; real and imaginary hyper-elliptic curve cryptography; divisibility, smoothness, and cryptographic applications; a variant of the Reidemeister-Schreier algorithm for the fundamental groups of Riemann surfaces; theta functions and algebraic curves
with automorphisms; enumerative geometry and string theory; and the cryptographical properties of extremal algebraic graphs.
