| Abstract | In this article, generalizations of the well-known Pohožaev and Pucci-Serrin identities and (as consequences of them) some non-existence results for Dirichlet problems with p (x)-Laplacian are obtained.The main ideas within this paper as well as the most important results obtained during the study are presented in Section 1.In Section 2, there are recalled the main results concerning the generalized Sobolev spaces (also known as Sobolev spaces with variable exponent)which will be used throughout this paper.In Sections 3 and 4, we will give some necessary technical results regarding the differential calculus in generalized Sobolev spaces and the differentiability properties of superposition operators between generalized Sobolev spaces (in the Marcus-Mizel direction).In Sections 5 and 6, a Pohožaev-type identity and a non-existence result obtained by Pucci and Serrin for a Dirichlet problem with p-Laplacian are generalized to a Dirichlet problem with p (x)-Laplacian. The Pohožaev identity and the non-existence Pohožaev’s result for Dirichlet problems with Laplacian are also generalized to the case of p (x)-Laplacian. In order to achieve this generalization, the technical results from Sections 3 and 4 are involved. |

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.
