If U is a subset of Y , we define the set f^{-1}(U) to be the set f^{-1}(U):=\left\{ x\in X:f(x)\in U \right\} . In other words, f^{-1}(U) consists of all the elements of X which map into U : f(x)\in U\Leftrightarrow x\in f^{-1}(U) . ...
(4) = f(g(4))=f(d) = \alpha.\\ Hence , the composition of functions f\circ g is given by: \underbrace{ f\circ g=\{(1,\alpha),(2,\alpha),(3,\gamma),(4,\alpha)\} }_{f\circ g \text{ is a function/set type, not value type}}\\ This is represented in the ...
A sentence from a formula can be obtained by inserting in the front of the formula enough quantifiers to bind all the free variables of the formula. The chapter also introduces one additional primitive notion that, although not strictly necessary, simplifies many statements of set theory. The ...
This book, the first of a three part series, consists of a set of entirely solved problems in mathematical analysis. Unlike other analysis problem books, it provides detailed solutions, often several pages long and complemented by drawings, to the probl
In theory, using inline functions can make your program faster because they eliminate the overhead associated with function calls. Calling a function requires pushing the return address on the stack, pushing arguments onto the stack, jumping to the function body, and then executing a return instruc...
In this paper, we show that there is a one-to-one correspondence between operator monotone functions on the nonnegative reals and finite Borel measures on ... P Chansangiam - 《Mathematics》 被引量: 3发表: 2013年 加载更多来源会议 2009 7th International Symposium on Intelligent Systems and ...
Let N be a finite set and z be a real-valued function defined on the set of subsets of N that satisfies z(S)+z(T)≥z(ST)+z(ST) for all S, T in N. Such a function is called submodular. We consider the problem max SN {a(S):|S|≤K,z(S) submodular}.Several hard combinat...

The factorization of short- and long-range physics [1] in hard-process cross sections constitutes the cornerstone of contemporary collider physics. While the short-range parts can be systematically calculated by the perturbative techniques of Quantum Chromodynamics (QCD) and electroweak theory, the long...
