| Abstract | For a proper cone $${{\mathcal K}\subset\mathbb{R}^n}$$ and its dual cone $${{\mathcal K}^*}$$ the complementary slackness condition $${\langle{\rm {\bf x}},{\rm {\bf s}}\rangle=0}$$ defines an n-dimensional manifold $${C({\mathcal K})}$$ in the space $${{\mathbb R}^{2n}}$$ . When $${{\mathcal K}}$$ is a symmetric cone, points in $${C({\mathcal K})}$$ must satisfy at least n linearly independent bilinear identities. This fact proves to be useful when optimizing over such cones, therefore it is natural to look for similar bilinear relations for non-symmetric cones. In this paper we define the bilinearity rank of a cone, which is the number of linearly independent bilinear identities valid for points in $${C({\mathcal K})}$$ . We examine several well-known cones, in particular the cone of positive polynomials $${{\mathcal P}_{2n+1}}$$ and its dual, and show that there are exactly four linearly independent bilinear identities which hold for all $${({\rm {\bf x}},{\rm {\bf s}})\in C({\mathcal P}_{2n+1})}$$ , regardless of the dimension of the cones. For nonnegative polynomials over an interval or half-line there are only two linearly independent bilinear identities. These results are extended to trigonometric and exponential polynomials. We prove similar results for Müntz polynomials. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
