  The growing importance of China in the global economy, particularly in production, trade, and finance, has led Chinese companies to become increasingly active in international capital markets. One key manifestation of this ...

• Bridging Classical and Modern Approaches to Thales' Theorem 

  Błaszczyk, Piotr; Petiurenko, Anna (Wydawnictwo Uniwersytetu Łódzkiego, 2026-04-24)

  In this paper, we reconstruct Euclid’s theory of similar triangles, as developed in Book VI of the Elements, along with its 20th-century counterparts, formulated within the systems of Hilbert, Birkhoff, Borsuk and Szmielew, ...

• Classical Logic, Uniformity, and Weak Excluded Middle in Non-Monotonic Proof-Theoretic Semantics 

  Piccolomini d’Aragona, Antonio (Wydawnictwo Uniwersytetu Łódzkiego, 2026-04-24)

  Non-monotonic base-extension semantics (nB-eS), a kind of non-monotonic proof-theoretic semantics (nPTS), is known to validate classical logic when its meta-logic is classical. Schroeder-Heister has remarked that classical ...

• An Elementary Proof of the Characterization Theorem for Conjunctive Multiple-Conclusion Consequence Relations 

  Taşdelen, İskender (Wydawnictwo Uniwersytetu Łódzkiego, 2026-04-15)

  We give a characterization theorem for multiple-conclusion consequence relations with the conjunctive reading of conclusions. As in the case of disjunctive multiple-conclusion consequence relations, we define consequence ...

• The Amalgamation Property in the Variety of Regular Double Stone Algebras: A Constructive View 

  Ledda, Antonio; Sankappanavar, Hanamantagouda P.; Vergottini, Gandolfo (Wydawnictwo Uniwersytetu Łódzkiego, 2026-04-24)

  In this paper we give a constructive proof that the variety of Boolean algebras has the strong amalgamation property by describing constructively the strong amalgams in the variety. Then, capitalizing on this construction, ...
