In mathematics, and specifically in functional analysis, the L p sum of a family of Banach spaces is a way of turning a subset of the product set of the members of the family into a Banach space in its own right. The construction is motivated by the classical L p spaces. [1]
In mathematics, Tonelli's theorem in functional analysis is a fundamental result on the weak lower semicontinuity of nonlinear functionals on L p spaces.As such, it has major implications for functional analysis and the calculus of variations.
In mathematics, Farkas' lemma is a solvability theorem for a finite system of linear inequalities. It was originally proven by the Hungarian mathematician Gyula Farkas . [ 1 ] Farkas' lemma is the key result underpinning the linear programming duality and has played a central role in the development of mathematical optimization (alternatively ...
This description assumes the ILP is a maximization problem.. The method solves the linear program without the integer constraint using the regular simplex algorithm.When an optimal solution is obtained, and this solution has a non-integer value for a variable that is supposed to be integer, a cutting plane algorithm may be used to find further linear constraints which are satisfied by all ...
In mathematical optimization, linear-fractional programming (LFP) is a generalization of linear programming (LP). Whereas the objective function in a linear program is a linear function, the objective function in a linear-fractional program is a ratio of two linear functions. A linear program can be regarded as a special case of a linear ...
Let u = u(x), x = (x 1, ..., x n) be a C 2 function which satisfies the differential inequality = + in an open domain (connected open subset of R n) Ω, where the symmetric matrix a ij = a ji (x) is locally uniformly positive definite in Ω and the coefficients a ij, b i are locally bounded.
In mathematics – specifically, in operator theory – a densely defined operator or partially defined operator is a type of partially defined function.In a topological sense, it is a linear operator that is defined "almost everywhere".
Again by the Poincaré lemma (and under its assumptions), gauge freedom is the only source of indeterminacy, so the field formulation is equivalent to the potential formulation if we consider the potential equations as equations for gauge equivalence classes. The potential equations can be simplified using a procedure called gauge fixing.
