ON THE NUMBER OF REAL SOLUTIONS OF A RANDOM POLYNOMIALZerosWe obtain bounds as a function of n, for the number of real solutions of the random algebraic equation Sigma(j-0)(n)a(j)x(j) = K-n where the coefficients a(j)'s are independent random variables and K-n is a sequence of...
Real number, in mathematics, a quantity that can be expressed as an infinite decimal expansion. The real numbers include the positive and negative integers and the fractions made from those integers (or rational numbers) and also the irrational numbers.
Rational solutions of Abel differential equations We study the rational solutions of the Abel equation x' = A(t)x(3) + B(t)x(2) where A and B is an element of C[t]. We prove that if deg(A) is even or deg(B... JL Bravo,LA Calderon,M Fernandez,... - 《Journal of ...
Bounds on the Number of Real Solutions to Polynomial Equations. We use Gale duality for complete intersections and adapt the proof of the fewnomial bound for positive solutions to obtain the bound e4+342(k2)nk for the n... Bates,Daniel,J.,... - 《International Mathematics Research Notices...

Irrational number, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals 2. A counterpart problem in measurement w
