How fast was wild wheat domesticated?
Prehistoric cultivation of wild wheat in the Fertile Crescent led to the selection of mutants with indehiscent (nonshattering) ears, which evolved into modern domestic wheat. Previous estimates suggested that this transformation was rapid, but our analyses of archaeological plant remains demonstrate that indehiscent domesticates were slow to appear, emerging approximately 9500 years before the ...
متن کاملThe Laplace Equation
Definition 1. Among the most important and ubiquitous of all partial differential equations is Laplace’s Equation: ∆u = 0, where the Laplacian operator ∆ acts on the function u : U → R (U is open in R) by taking the sum of the unmixed partial derivatives. For example: n = 1: ∆u = ∂ 2u ∂x2 = u = 0 In this simple case, the solution u = ax + b is found by integrating twice. n = 2: ∆u = ∂ 2u ∂x1 + ...
متن کاملHow the Alternating Sign Matrix Conjecture Was Solved, Volume 46, Number 6
Introduction Perusing the four volumes of Muir’s The Theory of Determinants in the Historical Order of Development, one might be tempted to conclude that the theory of determinants was well and truly beaten to death in the nineteenth century. In fact, the field is thriving, and it has continued to yield challenging problems of deceptive elegance and simplicity. The Alternating Sign Matrix Conje...
متن کاملInhomogeneous infinity Laplace equation ✩
We present the theory of the viscosity solutions of the inhomogeneous infinity Laplace equation ∂xi u∂xj u∂ 2 xixj u = f in domains in Rn. We show existence and uniqueness of a viscosity solution of the Dirichlet problem under the intrinsic condition f does not change its sign. We also discover a characteristic property, which we call the comparison with standard functions property, of the visc...
متن کاملThe Laplace transform method for Burgers’ equation
The Laplace transform method (LTM) is introduced to solve Burgers’ equation. Because of the nonlinear term in Burgers’ equation, one cannot directly apply the LTM. Increment linearization technique is introduced to deal with the situation. This is a key idea in this paper. The increment linearization technique is the following: In time level t , we divide the solution u(x, t) into two parts: u(...
