(15) This equation can be solved in terms of A-hypergeometric series in the sense of Gel’fand, Kapranov and Zelevinsky, [4]. Sturmfels =-=[13]-=- constructs the solutions explicitly in the form of power series. Loosely speaking, each of the n solutions to (15) can be written down as power series in se...
Such equations are known as algebraic equations, and the unknown is a number. The unknown in a differential equation is a function, and a differential equation will almost always involve this function and one or more derivatives of the function. For example, f 0.x/ D f .x/ is a simple...
In this paper we investigate the nature of the adapted solutions to a class of forward-backward stochastic differential equations (SDEs for short) in which the forward equation is non-degenerate. We prove that in this case the adapted solution can always be sought in an “ordinary” sense ove...
is a solution to our differential equation. You may be deeply skeptical of how we got here, and good for you if you are, but it’s easy to show that this is in fact a solution to our differential equation. Is this worth it? There are other ways to find a solution to our different...
What Is Needed for a Finite Element Analysis To solve partial differential equations with the finite element method, three components are needed: a discrete representation of a region, i.e. a mesh a partial differential equation boundary conditions that link the equation with the region This ...
However, even when unique solutions exist, the toolbox might not express the solutions in a symbolic form explicitly. For these reasons, you can choose from several approaches to solving equations: Find a complete set of solutions, including parameters and conditions on solutions. Find numerical ...

Moreover, our method is different from previous deep learning methods in that it is not necessary to explicitly compute the derivatives of a neural network with respect to input neurons in solving a differential equation. After detailing our method in Sections 2 and 3, we will demonstrate its ...
Hence, by performing a nested minimization of (17) within (13), we solve the problem at hand without explicitly dealing with the full operator T. We call this the Double Ritz Method. Algorithm 1 depicts its nested-loop optimization strategy that iterates separately either with elements in U ...
