जागदीशीव्याधिकरणम् (Jāgadīśvyādhikaraṇam)

This is a prakaraṇa text on the Nyāya theory of vyāpti written by Jagadīśa. The main theme of the work centres around the nature of vyāpti.Knowledge of vyāpti is the cause of inferential knowledge. If the definition of vyāpti is constructed in terms of avyābhicāritatva, then one could explain  avyābhicāritatva in five alternative ways. And none of these alternatives is acceptable, for this understanding of vyāpti would fail to account for kevalānvayi inference. In order to remove this problem, the definition of vyāpti is reconstructed as pratiyogivṛttidharmāvacchinna-pratiyogitākabhāvarupa vyādhikaraṇadharmāvacchinnabhāva. Jagadīśa examines this new definition of vyāpti and offers his justification, refuting all the possible objections.

सिद्धान्तलक्षणम् (Siddhānta Lakṣaṇam)

The final definition of vyāpti, known as siddhāntalakṣaṇa, has been explained by Jagadīśa in this work. The final definition of vyāpti is: where pratiyogyasāmānadhikaraṇya tāsāmānādhikaraṇatyantābhāvāpratiyogitāvacchedakabhacchinam does not hold, their vyāpti stays in the same locus. Raghunātha Śiromaṇi comments on this definition of vyāpti. Jagadīṣa further explains this final definition of vyāpti.

शब्दशक्तिप्रकाशिका (Śabdaśaktiprakāśikā (Part-1))

In this book Jagadīa Tarkālaṃkāra presents a detailed analysis of various aspects of śabdapramāṇa from the perspective of Navya-Nyāya. The book starts with a critical assessment of the views of Vaiśeṣika and Mīmāṃsaka philosophers with regard to the veridicality of śabda as a pramāṇa. This is followed by a discourse on the nature of meaningful words, the nature of prākṛti, pratya, nipāta. A definition of a sentence is formulated. The relation between word and meaning in its different aspects has been presented. The book ends with a discussion on the nature and different kinds of samāsa.

शब्दशक्तिप्रकाशिका (Śabdaśaktiprakāśikā (Vol-2))

In the second volume of Śabdaśaktiprakāśikā, Jagadīśa presents a detailed analysis of Prabhākara’s kāryānvitaśaktivāda and refutes this view. Jagadīśa defends the niravacchinna śaktivāda of the words like ākāśa etc. The view of Raghuntha Siromani with regard to the causal nexus of linguistic understanding has been refuted. Jagadisa offers an analysis of the nature of paribhāṣika śabda and argues that proper names given to individuals do not have śakti and they are to be treated as paribhāśaika śabda. Jagadīśa defends the view that śakti resides in all the three loci: the individual, the universal and the relation of samavāya that holds between an individual and the universal. Jagadīśa also refutes the Mīmāṃsaka view that the sentence has lakṣaṇā and the view of Ālaṃkārika regarding the vyāñjanā relation has been rejected. In this book, Jagadīśa offers a detailed analysis of different kinds of lakṣaṇā and in this context, one comes across a criticism of the Prabhākara thesis that the word having lakṣaṇā is not the cause of syntactic knowledge of the sentence. This book ends with an analysis of the nature of yogaruḍa śabda.
