In mathematics, Hodge theory, named after W. V. D. Hodge, is a method for studying the cohomology groups of a smooth manifold M using partial differential equations.The key observation is that, given a Riemannian metric on M, every cohomology class has a canonical representative, a differential form that vanishes under the Laplacian operator of the metric.
Below is the grading system found to be most commonly used in United States public high schools, according to the 2009 High School Transcript Study. [2] This is the most used grading system; however, there are some schools that use an edited version of the college system, which means 89.5 or above becomes an A average, 79.5 becomes a B, and so on.
Grading in education is the application of standardized measurements to evaluate different levels of student achievement in a course. Grades can be expressed as letters (usually A to F), as a range (for example, 1 to 6), percentages, or as numbers out of a possible total (often out of 100).
In the realm of US education, a rubric is a "scoring guide used to evaluate the quality of students' constructed responses" according to James Popham. [1] In simpler terms, it serves as a set of criteria for grading assignments.
Contract grading is a form of grading which results from cooperation between an instructor and their student(s), and entails completion of a contracted number of assignments of specified quality that correspond to specific letter grades. These contracts often contain the following two characteristics: First, there are no finite amount of, say ...

Yet another definition of a Hodge structure is based on the equivalence between the -grading on a complex vector space and the action of the circle group U(1). In this definition, an action of the multiplicative group of complex numbers C ∗ {\displaystyle \mathbb {C} ^{*}} viewed as a two-dimensional real algebraic torus, is given on H ...
