When you think about shapes and Points in a flat space, it's easy to imagine dots and lines. But what happens when we take those dots to a different world, a projective space? It’s like going from a flat pancake to a fancy layer cake where every slice has a different flavor!
The Basics of Projective Space
In our projective space, general points have some special powers. These points can define unique curves, which are just fancy words for shapes that smoothly connect dots. These curves can be created using different methods, sort of like cooking a meal with various recipes. We can use algebra, Geometry, or even some clever arguments that resemble a magic trick!
Veronese Surfaces?
What AreNow, we introduce these intriguing creatures called Veronese surfaces. Think of them like patterned tablecloths spread across a grand dining table. They come in different flavors, depending on how many times we "fold" or "wrap" our points. A uple here means how many times we play with our points.
The fun part? Each unique arrangement of points creates its own special Veronese surface. And guess what? Some people have been trying to figure out just how many surfaces can be formed when we throw in a random number of points. It’s like counting how many different sandwiches you can make from a set of ingredients!
Magic from the Past
Long ago, a clever person figured out that a particular arrangement of points shows a precise number of surfaces. They used a theory to reveal that every group of points magically creates a specific number of surfaces. But that theory didn’t cover every scenario. Just like a magician who has a few tricks up their sleeve, there are still many questions left unanswered.
The Challenge of Thirteen Points
Let’s take a wild step forward. What if we have thirteen points? Those general points can create a surprising number of Veronese surfaces-more than you might think! We're going to dig into the process that helps us understand how to count them.
The Journey to Understand Surfaces
First, we want to explore connections, just like a network of friends. We will use correspondences-these are fun ways to connect different ideas and shapes together. Think of it as finding out how your friends know each other in a big party!
In our case, we are trading the job of counting surfaces for another task: counting special groups of points called singular Triads. A bit like counting how many pairs of socks you have-only, they need to meet certain conditions!
The Missing Piece
In our quest, we stumble upon a tiny obstacle-something not quite fitting right, like a sock that’s just too big. The problem arises because we need to connect to something called a vector bundle, which is a fancy way to describe a collection of shapes. Trouble is, the collection isn’t always smooth and neat.
So what do we do? We change our approach and swap out our current idea for something much better. We introduce a new space called the space of complete triangles. Just as triangles create sturdy foundations, this new space helps us understand the geometry better.
Triangles to the Rescue
Now, we dive deep into triangles, which helps us navigate our understanding. With this fresh perspective, we gather more tools to count our special triads. It’s finally time to connect the dots, quite literally!
So, these triangles lead us to a happy place where things work out neatly. We find out there’s no excess confusion-like making sure each sock in your drawer is a perfect match!
Overcoming the Extra Confusion
Yet, we come across a twist in our adventure. We must deal with some extra stuff-like those random mismatched socks! Our calculation still has some “excess” that we need to remove.
To tackle this, we switch our framework again to a more organized approach, using another bundle we call the space of singular quintic pencils. It's like creating a new color palette for our art project-much easier than working with the old mess!
Finding the Right Count
So, armed with our new tools, we finally set out to get the right count! By cleverly combining our findings, we start getting clearer answers about how numerous these Veronese surfaces are.
Then, we compute some critical values, almost like checking if we have enough eggs to bake a cake! Over various methods, we make sure all our numbers add up in a fun way.
The Questions That Remain
Now, after our grand exploration, we have a list of questions that remain unanswered! Isn’t that the life of scientists?
We ponder over whether all the great connections we’ve found hold true for different cases. Imagine tasting a dish from several angles-will it taste the same each time?
Also, we wonder if we can confirm earlier examples using powerful math tools. And could our findings change with different flavors of ingredients?
The Finale
And there you have it! While we started out in a flat world, we journeyed through projective Spaces, discovering Veronese surfaces and the magic of counting. Let’s give a round of applause to geometry and algebra for making our adventure so delightful!
So next time you have a group of points, think about how they might transform into shapes beyond your wildest dreams! Who knows, you might just stumble upon the next great mathematical discovery!
Title: Counting 3-uple Veronese surfaces
Abstract: This paper culminates in the count of the number of 3-Veronese surfaces passing through 13 general points. This follows the case of 2-Veronese surfaces discovered by Coble in the 1920's. One important element of the calculation is a direct construction of a space of "complete triangles." Our construction is different from the classical ordered constructions of Schubert, Collino and Fulton, as it occurs directly on the Hilbert scheme of length 3 subschemes of the plane. We transport the enumerative problem into a 26-dimensional Grassmannian bundle over our space of complete triangles, where we perform Atiyah-Bott localization. Several important questions arise, which we collect at the end of the paper.
