Yes, there might be. Fanfiction websites are full of various creative works. You could try searching on platforms like Archive of Our Own or FanFiction.net. Just type in 'harry is a math genius' in the search bar and see what comes up.
One possibility is that the math genius could be a Muggle - born who brings a different perspective to the wizarding world. They might use math to analyze spells and find more efficient ways of casting them. They could also use their skills in arithmancy, which already has some mathematical elements in the Harry Potter series, and take it to a whole new level.
Perhaps the math genius gets recruited by a secret society within Hogwarts that is dedicated to exploring the connection between magic and numbers. They go on adventures to find magical artifacts that are said to be related to ancient math - based magic. Along the way, they face challenges from dark wizards who want to use this knowledge for evil purposes.
One possible fanfiction could be about a character who uses their math skills from the Numb3rs world to solve magical equations in the Harry Potter universe. For example, they might figure out a way to calculate the exact amount of magic needed for a complex spell, just like how mathematicians in Numb3rs solve complex crimes using numbers.
Well, in the context of fanfiction, a math genius could create a new form of magic that is based on mathematical principles. In the Harry Potter world, magic is often more about incantations and wand - waving, but a math - based magic could be introduced. For instance, the math genius could develop a spell that is activated by solving a complex equation in real - time. This would add a whole new dimension to the magical world of Harry Potter, while also bringing in the intellectual and analytical aspects of Numb3rs. They could also use math to decrypt ancient magical runes that have been long forgotten, as they might see patterns in the symbols that others miss, just like how they solve number - based mysteries in Numb3rs.
I'm not sure of a specific fanfiction that combines all those elements exactly. You could try searching on major fanfiction websites like Fanfiction.net or Archive of Our Own. Maybe start by looking for Harry Potter crossovers and then filter for mentions of'math genius' and 'Stargate' within those results.
Sorry, I can't directly recommend a specific 'harry is a math genius' fanfiction as I don't have a list of them at hand. But as I said before, you can search for it on fanfiction platforms.
One interesting crossover could be the use of Numb3rs' math concepts to solve magical problems in the Harry Potter world. For example, using probability theories to predict the outcome of a Quidditch match based on the players' past performances and current conditions.
๐I have a novel that perfectly meets your requirements, and it's called "One Key Upgrade of the Super Disintegration System". This book is about a third-year student, Jiang Hao, who suddenly obtained the decomposition and synthesis system. He can decompose anything and obtain the corresponding mathematical crystals. He used to be a school health worker, but he hid an amazing mathematical talent. Not only did this novel contain exciting mathematical explorations, but it also contained thrilling technological adventures. It was definitely a good book that should not be missed. I hope it suits your taste. Muah ~๐
