1. Geometric and Algebraic Methods for PDEs

The geometric theory of differential equations uses jet spaces, Cartan distributions, and Lie transformations to analyze systems of partial differential equations (PDEs) from a geometric and algebraic viewpoint. This approach provides a framework for understanding the structure, compatibility, and integrability of PDEs using concepts like Spencer cohomology and differential operators' algebra.
This manifesto emphasizes that differential equations are not just analytic objects but have rich geometric structures that can be exploited for better theoretical understanding and computational methods.

2. Structure-Preserving Numerical Methods

A major development in computational differential equations is the focus on structure-preserving discretizations, also known as geometric numerical integration. These methods are designed to preserve key geometric and topological properties of the original continuous differential equations, such as symplectic structure, invariants, or conservation laws, leading to qualitatively and quantitatively more accurate simulations over long times.
This approach contrasts with classical numerical methods that may not respect the underlying geometry, potentially leading to numerical artifacts or loss of important qualitative features.

3. Unified Computational Frameworks

Computational differential equations are increasingly presented through unified frameworks that combine symbolic and numerical aspects, reflecting the dual nature of differential equations as infinite-dimensional (continuous) and finite-dimensional (discrete) objects. For example, Galerkin methods provide a systematic way to discretize and solve differential equations numerically while maintaining mathematical rigor.
This manifesto advocates for blending mathematical modeling and computation seamlessly to handle complex differential equations in science and engineering effectively.

4. Geometric Interpretation of Classical Equations

Certain classical differential equations, such as second-order linear ODEs of the form $u^{\prime \prime}(x)+h(x) u(x)=0$, can be interpreted geometrically as geodesic equations in hyperbolic geometry. This geometric viewpoint offers new insights and solution methods by linking differential equations to the geometry of curved spaces.
Extending these ideas to complex and Lorentzian geometries further enriches the understanding and potential computational techniques for differential equations.

5. Computer Algebra and Symbolic Computation

Computer algebra systems incorporate geometric and algebraic methods to solve and analyze differential equations symbolically. This includes symmetry analysis, local analysis, differential ideals, and Galois theory, which provide powerful tools to understand solution spaces, integrability, and transformations of differential equations.
The manifesto here is that symbolic computation complements numerical methods by providing exact, structural insights that can guide and improve computational approaches.

The application of geometric differential equations in cloud computing facilitates the advanced visualization and animation of complex data, particularly in deforming surfaces towards minimal surfaces and managing Gaussian curvature in distributed environments.

Cloud computing significantly enhances the numerical analysis, code verification, and interactive visualization of a wide range of complex scientific and engineering phenomena, from fluid dynamics and heat transfer to financial modeling and electromagnetic fields, by providing a powerful and accessible platform for simulations, animations, and the study of various linear and nonlinear partial differential equations.
