Showing the flag

The Saying/Showing Distinction in Early Wittgenstein and Its Implications

 Jafar Morvarid[1]  In this paper, I shall try to clarify the saying/showing distinction and to emphasize the role of this distinction in constructing a coherent picture of language and the world. In order to properly understand the differences between the sayable and the showable, I will throw light on the limits of language and the world. I will explain why it is impossible to say the showab...

The French Flag Model

The French flag model represents how embryonic cells receive and respond to genetic information and subsequently differentiate into patterns. Created by Lewis Wolpert [5] in the late 1960?s, the model uses the French tricolor flag as visual representation to show how embryonic cells can interpret genetic code to create the same pattern even when certain pieces of the embryo are removed. Wolpert...

1.1. QCoh on a stack. We know that QCoh forms a stack, i.e., sheaf of groupoids, over Schfpqc(S) for any scheme S. Thus if we have an fpqc sheaf of groupoids X over S, we can define QCoh(X ) as maps of sheaves X → QCoh on Schfpqc(S). By 2-Yoneda, this definition agrees with the usual notion of quasicoherent sheaves if X is a scheme. For various other (usually equivalent) definitions in the case...

Flag algebras

Asymptotic extremal combinatorics deals with questions that in the language of model theory can be re-stated as follows. For finite models M, N of an universal theory without constants and function symbols (like graphs, digraphs or hypergraphs), let p(M, N) be the probability that a randomly chosen sub-model of N with |M | elements is isomorphic to M . Which asymptotic relations exist between t...
