==재미있는 사실==
 +
 
 +
Raussen and Skau: In the introduction to your delightful book Rational Points on Elliptic Curves that you coauthored with your earlier Ph.D. student Joseph Silverman, you say, citing Serge Lang, that it is possible to write endlessly on elliptic curves. Can you comment on why the theory of elliptic curves is so rich and how it interacts and makes contact with so many different branches of mathematics? Tate: For one thing, they are very concrete objects. An elliptic curve is described by a cubic polynomial in two variables, so they are very easy to experiment with. On the other hand, elliptic curves illustrate very deep notions. They are the first nontrivial examples of abelian varieties. An elliptic curve is an abelian variety of dimension one, so you can get into this more advanced subject very easily by thinking about elliptic curves.
 +
 
 +
On the other hand, they are algebraic curves. They are curves of genus one, the first example of a curve which isn’t birationally equivalent to a projective line. The analytic and algebraic relations which occur in the theory of elliptic curves and elliptic functions are beautiful and unbelievably fascinating. The modularity theorem stating that every elliptic curve over the rational field can be found in the Jacobian variety of the curve which parametrizes elliptic curves with level structure its conductor is mind-boggling.

재미있는 사실

Raussen and Skau: In the introduction to your delightful book Rational Points on Elliptic Curves that you coauthored with your earlier Ph.D. student Joseph Silverman, you say, citing Serge Lang, that it is possible to write endlessly on elliptic curves. Can you comment on why the theory of elliptic curves is so rich and how it interacts and makes contact with so many different branches of mathematics? Tate: For one thing, they are very concrete objects. An elliptic curve is described by a cubic polynomial in two variables, so they are very easy to experiment with. On the other hand, elliptic curves illustrate very deep notions. They are the first nontrivial examples of abelian varieties. An elliptic curve is an abelian variety of dimension one, so you can get into this more advanced subject very easily by thinking about elliptic curves.

On the other hand, they are algebraic curves. They are curves of genus one, the first example of a curve which isn’t birationally equivalent to a projective line. The analytic and algebraic relations which occur in the theory of elliptic curves and elliptic functions are beautiful and unbelievably fascinating. The modularity theorem stating that every elliptic curve over the rational field can be found in the Jacobian variety of the curve which parametrizes elliptic curves with level structure its conductor is mind-boggling.

  61. Abelian Varieties can be viewed as generalizations of elliptic curves.[22]
  62. General purpose Elliptic Curve Cryptography (ECC) support, including types and traits for representing various elliptic curve forms, scalars, points, and public/secret keys composed thereof.[23]
  63. This crate provides traits for describing elliptic curves, along with types which are generic over elliptic curves which can be used as the basis of curve-agnostic code.[23]
  64. Elliptic curves are a very important new area of mathematics which has been greatly explored over the past few decades.[24]
  65. In 1994 Andrew Wiles, together with his former student Richard Taylor, solved one of the most famous maths problems of the last 400 years, Fermat's Last Theorem, using elliptic curves.[24]
  66. In the last few decades there has also been a lot of research into using elliptic curves instead of what is called RSA encryption to keep data transfer safe online.[24]
  67. The elliptic curves corresponding to whole number values of a between -2 and 1 and whole number values of values of b between -1 and 2.[24]
  68. This book is an introduction to the theory of elliptic curves, ranging from elementary topics to current research.[25]
  69. The two additional chapters concern higher-dimensional analogues of elliptic curves, including K3 surfaces and Calabi-Yau manifolds.[25]
  70. Two new appendices explore recent applications of elliptic curves and their generalizations.[25]
  71. Please see our tracking issue for additional elliptic curves if you are interested in curves beyond the ones listed here.[26]
  72. Each elliptic curve point is associated with a particular parameter set.[27]
  73. We use elliptic curves because they provide a cryptographic group, i.e. a group in which the discrete logarithm problem (discussed below) is hard.[28]
  74. By convention, elliptic curve groups are written additively.[28]
  75. This is called the elliptic curve discrete log assumption.[28]
  76. In the case of a cryptographically secure elliptic curve, the isomorphism is hard to compute in the G→Fq​ direction because the elliptic curve discrete log problem is hard.[28]
  77. Elliptic Curves Elliptic curves are groups created by de(cid:12)ning a binary operation (addition) on the points of the graph of certain polynomial equations in two variables.[29]
  78. Choosing random coe(cid:14)cients results in groups with random orders near p. 1 One can use elliptic curves to factor integers, although probably not RSA moduli.[29]
  79. There is a probabilistic algorithm for proving primality that uses elliptic curves.[29]
  80. discrete logarithm problem is harder for elliptic curve groups than for the integers modulo p, permitting smaller parameters and faster algo- rithms.[29]
  81. The use of elliptic curves in cryptography was independently suggested by Neal Koblitz and Victor Miller in 1985.[30]
  82. From a high level, Crypto++ offers a numbers of schemes and alogrithms which operate over elliptic curves.[30]
  83. For cryptographic computational purposes, elliptic curves are represented in several different forms.[31]
  84. You don't need to know much algebra to understand how elliptic curve cryptography works.[32]
  85. This method can give all such functions and only them; it's not hard to see that only meromorphic functions with this property are allowed on elliptic curve.[33]
  86. In particular, elliptic curves coincide with their Jacobian and that's another explanation for the additive law.[33]
  87. Indeed elliptic curves are dominating the cryptography landscape but for people other than Mathematicians the logic behind this may not be so obvious.[34]
  88. I am therefore writing this post to give a gentle introduction in elliptic curves for people with basic mathematical background and explain why they are so popular amongst cryptographers.[34]
  89. This is exactly where elliptic curves become relevant in cryptography.[34]
  90. These groups formed by elliptic curves are the groups used for building elliptic curve cryptosystems.[34]
  91. Elliptic curve cryptography (ECC) uses the mathematical properties of elliptic curves to produce public key cryptographic systems.[35]
